The overshoot code introduced in a change `Fix B/W + rasterization of subglyphs with different drop-out modes.' (from + 2009-06-18) violated this, accessing `ras.cProfile->flags' + unconditionally just before calling `End_Profile' (which then + detected that `cProfile' is uninitialized and didn't touch it). + + This was harmless, and was not detected by valgrind before because + the objects were allocated on the `raster_pool', which was always + initialized. With recent change to allocate raster buffers on the + stack, valgrind now reported this invalid access. + + * src/raster/ftraster.c (Convert_Glyph): Don't access an + uninitialized `cProfile'. + +2015-01-14 Behdad Esfahbod <behdad@behdad.org> + + [smooth] Fix uninitialized memory access. + + Looks like `ras.span_y' could always be used without initialization. + This was never detected by valgrind before because the library-wide + `raster_pool' was used for the worker object and `raster_pool' was + originally zero'ed. But subsequent reuses of it were using `span_y' + uninitialized. With the recent change to not use `render_pool' and + allocate worker and buffer on the stack, valgrind now detects this + uninitialized access. + + * src/smooth/ftgrays.c (gray_raster_render): Initialize + `ras.span_y'. + +2015-01-14 Behdad Esfahbod <behdad@behdad.org> + + [base] Don't initialize unused `driver->glyph_loader'. + + * src/base/ftobjs.c (Destroy_Driver): Don't call + `FT_GlyphLoader_Done'. + (FT_Add_Module): Don't call `FT_GlyphLoader_New'. + +2015-01-14 Behdad Esfahbod <behdad@behdad.org> + + [base] Don't allocate `library->raster_pool' anymore. + + It's unused after the following commits: + + [raster] Allocate render pool for mono rasterizer on the stack. + [raster] Remove 5-level gray AA mode from monochrome rasterizer. + + The value of FT_RENDER_POOL_SIZE still serves the purpose it used to + serve, which is, to adjust the pool size.
