Bug#691109: libc6: memcpy-ssse3.S accesses invalid memory address area under certain conditions.
This bug appears again.
This time, it is in the context of debugging mozilla thunderbird mail client for
linux.
During running of debug build of mozilla thunderbird under valgrind, I observed these warnings, one of which is shown below.
When I filed this problem about valgrind at kde site,
the problem of memcpy-ssse3.S is reported not to happen under 64-bit Ubuntu according to
https://bugs.kde.org/show_bug.cgi?id=307828#c4
I filed a separate entry as suggested there anyway.
https://bugs.kde.org/show_bug.cgi?id=311407
The proble is for real.
I can reliably reproduce this bogus warning using the
sample program, test-copy.c, attached in
http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=test-copy.c;att=2;bug=691109
These bogus warning messages are really annoying when one tries to hunt down real problems.
I hope this helps.
TIA
