Thank you for the patch. I did finally manage to get a seemingly
stable MySQL on amd64. Specifically, by converting from pure64 to
your gcc-3.4 repository. Thank you for that too!
After patching the sources, MySQL failed on the pure64 (3.3) archive
whether compiled from upstream MySQL sources or Alioth sources, and
whether I used gcc-3.3 or gcc-3.4.
Compiling (with gcc-3.4) on the gcc-3.4 archive did the trick though.
Either some of your patches to the libs, or simply compiling those
libs with gcc-3.4, seems to have solved the problems I was seeing.
The problem I had been seeing was when I'd do a "make test" after a
"make", it would usually work. But if I ran it over and over again in
a loop, some one or another of the 206 tests run by "make test" would
fail once every 15-20 times through the loop. It was a different test
that would fail each time, and which iteration of the tests would fail
also seemed random.
This was reproducible on two separate machines, one of which has had
extensive memory testing, so I don't think it's dodgy hardware.
Compiling and running on a gcc-3.4-archive box ran rock solid, making
it through ~250 iterations of "make test" without an error before I
stopped it.
It gives me more faith in the gcc-3.4 archive for everything, since
the differences presumably are in one of the libraries used by MySQL.
Those would be:
% ldd sql/mysqld
librt.so.1 => /lib/librt.so.1
libdl.so.2 => /lib/libdl.so.2
libcrypt.so.1 => /lib/libcrypt.so.1
libnsl.so.1 => /lib/libnsl.so.1
libpthread.so.0 => /lib/libpthread.so.0
libstdc++.so.6 => /usr/lib/libstdc++.so.6
libm.so.6 => /lib/libm.so.6
libgcc_s.so.1 => /lib/libgcc_s.so.1
libc.so.6 => /lib/libc.so.6
/lib/ld-linux-x86-64.so.2 => /lib/ld-linux-x86-64.so.2
%
So, thanks again for your work!
