Running tests on HPPA results in a segmentation fault when running test_fork.rb.

The downstream bug report at https://bugs.gentoo.org/show_bug.cgi?id=388123 has all the details and the full build log.

Please give me C level backtrace.

Ruby on hppa is broken because hppa (at least last time I checked) was using a LinuxThreads-based thread implementation instead of NPTL.

Maybe it should not crash, but I don't expect that you will reach a working state anyway.

Not true at least on Gentoo/HPPA which has been using NPTL. So at least that is not a hurdle. I'll have to check for the backtrace, I can't produce one myself.

It looks like this got fixed with http://bugs.ruby-lang.org/issues/5488, we can no longer reproduce this in the latest version of ruby 1.9.3.
