Re: Reproducible random python crash.
Any idea what might be the cause? No. I looked at two core dumps briefly. In the first, it looked like the PIC register value was corrupt causing a transfer to page 0. In the second, there wasn't any backtrace info (both pc and rp were 0). Unfortunately, this doesn't say much. It would be fantastic if you could narrow this down. Dave -- J.

Re: Reproducible random python crash.
Kyle, Helge, John, James, Could I get each of you to follow this recipe and tell me if python crashes or hangs randomly during the execution of the last step? Recipe: mkdir -p ~/python-test cd ~/python-test apt-get update apt-get build-dep xmms2 apt-get source xmms2 cd xmms2_0.6DrMattDestruction ./waf configure --nocache --prefix=/usr --with-mandir=/usr/share/man --with-perl-archdir=/usr/lib/perl5 --with-perl-binary=/usr/bin/perl --with-ruby-archdir=/usr/lib/ruby/1.8/hppa-linux --with-ruby-libdir=/usr/lib/ruby/1.8 --without-optionals=python --without-plugins=mac Running the last step on a 2.6.26-1-parisc64-smp kernel results in random behaviour ranging from sigsegv, sigill, sigtrap, and a hang. Given that each of you might run it on a different kernel, I was hoping to see if the behaviour is the same across different kernels. I ran the apt-get though configure commands several times with no failures on Linux mx3210 2.6.30.5 #7 Wed Aug 19 17:31:54 EDT 2009 parisc64. So, it looks like the problem is SMP specific. Same kernel with SMP config on gsyprf11 resulted in random segs and hangs. The hangs may depend on the presence of cached data used by configure. I booted 2.6.30.5 from gsyprf11 because I had one random segv and one command hang while running the GCC testsuite. I suspect that some hangs are due to dropped signals. I'm tempted to try the sequence with 2.6.22.19. Dave -- J.
