I don't know whether this is a Dialogic Diva Fax problem or Glibc problem. With this commit, fax sent is corrupted. Reverting the commit solves the problem. I'm on latest glibc (dbf3a06904168417a05882a871342e7a9ee3b383) and it has the same problem, so I bisected to this commit causing the issue. I've tried all versions of DIVA including the latest Diva4Linux_installer_9.5-110-13.bin and dssdk-gcc4x-110.2555-1.x86_64.rpm Linux version is 2.6.33 gcc version 4.4.5 20100925 (prerelease) (GCC) GNU C Library stable release version 2.11.1, by Roland McGrath et al. (OK) GNU C Library development release version 2.12.90, by Roland McGrath et al. (bad) I've attached two images. One good and a corrupted image received. 6fb8cbcb58a29fff73eb2101b34caa19a7f88eba is the first bad commit commit 6fb8cbcb58a29fff73eb2101b34caa19a7f88eba Author: H.J. Lu <hongjiu.lu@intel.com> Date: Wed Jun 30 08:26:11 2010 -0700 Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7 This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7.
