Version|7.6 |7.8
--- Comment #2 from Mark <markghayden@???> 2009-04-21 20:14:41 ---
(1) I haven't tried 7.9. Actually, I looks as though I was incorrect on the
version. I'm using 7.8-2 (Debian testing).
(2) It doesn't look like a stack problem to me from the gdb stacktrace below or
the valgrind output of the test program.
I hope the small test program is helpful for you.
best, Mark
