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.
