The triggering code is the following: + + header+=11; + if (*header != '4') return(0); header++; + if (*header != ',') return(0); header++; + + What happens is that gcc might optimize a little too agressively, and + you end up with an extra incrementation when *header != '4'. + + We recommend that you upgrade gcc to as high a 3.x version as you can. + +- According to multiple problem reports, some of our message digest + implementations trigger bug[s] in code optimizer in gcc 3.3 for sparc64 + and gcc 2.96 for ppc.

Reason: the BN_kronecker test calls BN_generate_prime() +which itself hangs. The reason could be tracked down to the bn_mul_comba8() +function in bn_asm.c. At some occasions the higher 32bit value of r[7] +is off by 1 (meaning: calculated=shouldbe+1). Further analysis failed, +as no debugger support possible at +O3 and additional fprintf()'s +introduced fixed the bug, therefore it is most likely a bug in the +optimizer. +The bug was found in the BN_kronecker test but may also lead to +failures in other parts of the code. +(See Ticket #426.) + +Workaround: modify the target to +O2 when building with no-asm. + +* Problems building shared libraries on SCO OpenServer Release 5.0.6 + with gcc 2.95.3 + +The symptoms appear when running the test suite, more specifically +test/ectest, with the following result: + +OSSL_LIBPATH="`cd ..; pwd`"; LD_LIBRARY_PATH="$OSSL_LIBPATH:$LD_LIBRARY_PATH"; DYLD_LIBRARY_PATH="$OSSL_LIBPATH:$DYLD_LIBRARY_PATH"; SHLIB_PATH="$OSSL_LIBPATH:$SHLIB_PATH"; LIBPATH="$OSSL_LIBPATH:$LIBPATH"; if [ "debug-sco5-gcc" = "Cygwin" ]; then PATH="${LIBPATH}:$PATH"; fi; export LD_LIBRARY_PATH DYLD_LIBRARY_PATH SHLIB_PATH LIBPATH PATH; ./ectest +ectest.c:186: ABORT + +The cause of the problem seems to be that isxdigit(), called from +BN_hex2bn(), returns 0 on a perfectly legitimate hex digit. Further +investigation shows that any of the isxxx() macros return 0 on any +input. A direct look in the information array that the isxxx() use, +called __ctype, shows that it contains all zeroes... + +Taking a look at the newly created libcrypto.so with nm, one can see +that the variable __ctype is defined in libcrypto's .bss (which +explains why it is filled with zeroes): + +$ nm -Pg libcrypto.so | grep __ctype +__ctype B 0011659c +__ctype2 U + +Curiously, __ctype2 is undefined, in spite of being declared in +/usr/include/ctype.h in exactly the same way as __ctype. + +Any information helping to solve this issue would be deeply +appreciated. + +NOTE: building non-shared doesn't come with this problem. + +* ULTRIX build fails with shell errors, such as "bad substitution" + and "test: argument expected" + +The problem is caused by ULTRIX /bin/sh supporting only original +Bourne shell syntax/semantics, and the trouble is that the vast +majority is so accustomed to more modern syntax, that very few +people [if any] would recognize the ancient syntax even as valid. +This inevitably results in non-trivial scripts breaking on ULTRIX, +and OpenSSL isn't an exclusion. Fortunately there is workaround, +hire /bin/ksh to do the job /bin/sh fails to do. + +1. Trick make(1) to use /bin/ksh by setting up following environ- + ment variables *prior* you execute ./Configure and make: + + PROG_ENV=POSIX + MAKESHELL=/bin/ksh + export PROG_ENV MAKESHELL + + or if your shell is csh-compatible: + + setenv PROG_ENV POSIX + setenv MAKESHELL /bin/ksh + +2. Trick /bin/sh to use alternative expression evaluator. Create + following 'test' script for example in /tmp: + + #!/bin/ksh + ${0##*/} "$@" + + Then 'chmod a+x /tmp/test; ln /tmp/test /tmp/[' and *prepend* + your $PATH with chosen location, e.g. PATH=/tmp:$PATH. Alter- + natively just replace system /bin/test and /bin/[ with the + above script. + +* hpux64-ia64-cc fails blowfish test. + +Compiler bug, presumably at particular patch level. It should be noted +that same compiler generates correct 32-bit code, a.k.a. hpux-ia64-cc +target. Drop optimization level to +O2 when compiling 64-bit bf_skey.o. + +* no-engines generates errors. + +Unfortunately, the 'no-engines' configuration option currently doesn't +work properly. Use 'no-hw' and you'll will at least get no hardware +support. We'll see how we fix that on OpenSSL versions past 0.9.8. + +* 'make test' fails in BN_sqr [commonly with "error 139" denoting SIGSEGV] + if elder GNU binutils were deployed to link shared libcrypto.so. + +As subject suggests the failure is caused by a bug in elder binutils, +either as or ld, and was observed on FreeBSD and Linux. There are two +options. First is naturally to upgrade binutils, the second one - to +reconfigure with additional no-sse2 [or 386] option passed to ./config. + +* If configured with ./config no-dso, toolkit still gets linked with -ldl, + which most notably poses a problem when linking with dietlibc. + +We don't have framework to associate -ldl with no-dso, therefore the only +way is to edit Makefile right after ./config no-dso and remove -ldl from +EX_LIBS line. -- cgit v1.2.3
