Sorry, I get it only when configuring with '-O3 -DUNALIGNED_OK' (I thought I mentioned that already...) > Can you tell me what exactly I need to do to get the byte-51 undef > error, including details of what distro you're using? Ubuntu Gutsy and Intrepid, both x86_64, zlib-1.2.3.3-ubuntu5, although I can reproduce even with zlib-1.2.3. The key is to use both -O3 and -DUNALIGNED_OK. Ciao, Dscho |

Going round in circles here. > Your hint with VALGRIND_CHECK_MEM_IS_DEFINED() showed indeed that valgrind > thinks that the single byte at offset 51 (in a buffer of 58) is undefined. I just spent some time chasing this. I cannot reproduce the byte-51-is- undefined problem. It only shows that 58 and later are undefined, which is as expected. This is with various combinations of 32-bit and 64-bit builds, all optimisation levels, and with the system installed zlib and a from-source zlib. This is on x86_64, openSUSE 11.0, gcc (SUSE Linux) 4.3.1 20080507. Can you tell me what exactly I need to do to get the byte-51 undef error, including details of what distro you're using? J |
