Here is the gdb output: (gdb) run tests/generate.rb Starting program: /usr/bin/ruby tests/generate.rb (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [Thread debugging using libthread_db enabled] [New Thread -1210980160 (LWP 5975)] (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) Loaded suite tests/generate Started Program received signal SIGSEGV, Segmentation fault.

/usr/lib/libruby1.8.so.1.8 #253 0x080486bd in main () (gdb) I get very similar stack traces from 3 out of 4 of my unit test runs.

I will try to build a small reproducible test case but it may take a while. __ Marc On Thu, 2007-30-08 at 20:13 -0400, Dan Janowski wrote: > Marc, > > No surprise here!
