Subject: Strange segfault on Linux with test-unit

Hi all,

Ruby 1.8.2 (built with --enable-pthread)
Suse Linux 9.3 Pro
sys-proctable 0.7.0

I've getting some strange behavior with the test cases for the Linux
version of sys-proctable.  There are two test cases in particular that
are the issue: tc_linux.rb and tc_all.rb.

Running the tc_linux.rb script causes a segfault.  Now, tc_linux.rb
does a 'require "tc_all"' internally.  If I comment that out, then
running tc_linux.rb works fine.

Initially, I thought that must mean there's a problem in tc_all.rb.
But, if I run tc_all.rb by itself, it works fine as well.  So, each
test case works fine individually, but fails if I try to have one
require the other internally.

Within linux.c I commented out all of the code for ProcTable.ps and
ProcTable.fields, having them do nothing except return nil.  After
that, I ran tc_linux.rb again and got this error:

/usr/local/lib/ruby/1.8/test/unit.rb:285: [BUG] Segmentation fault
ruby 1.8.2 (2004-12-25) [i686-linux]

Aborted

Where line 285, part of the at_exit definition, is: exit
Test::Unit::AutoRunner.run($0 != "-e" && $0)

Any ideas on this one?

Regards,

Dan
