Thanks for the info. Can you get a backtrace with gc 6.8? See http://www.gnu.org/software/guile/manual/html_node/Reporting-Bugs.html#Reporting-Bugs for instructions, but instead of "backtrace", enter "thread apply all backtrace". Thanks!

I'll try the prerelease on both machines and report back.

I built and used libgc 6.8. On a side note, I was able to use begin-thread successfully on a Debian machine after following a similar build process but using libgc 7.1.

Hi Jason. What version of libgc are you using? Is it from the distro or did you compile it yourself?

Also, can you try a 2.0.2 prerelease, from here: http://hydra.nixos.org/build/1123775/download/1/guile- ?

Having created an account, let me add a little more information. I'm on Ubuntu 10.04, kernel version 2.6.32-28-generic-pae, and I compiled Guile with GCC 4.4.3 using no special flags.

Any way I use (begin-thread . . .) I get a segfault. I may be using it incorrectly, of course, but a segfault is probably not the best result.


Here's a sample session:

I'm happy to supply more information if needed.
