Hi,
I am having problems using libguile in a multi-threaded environment,
which boils down to the following small test case, which fails with a
segmentation fault with guile-2.0.9:
#include
#include
void *guile_wrapper (void *data) {
scm_c_eval_string ("(display \"Hello\n\")");
return NULL;
Hi,
I have never used the pthread library directly, but would it be
possible for your program to use scm_spawn_thread instead? (according
to the manual, it starts a new thread in guile mode, but I guess it
needs to be run in guile mode as well)

The code looks fine to me. It seems that there's a bug in guile --
when I insert one second sleep between the two invocations of
pthread_create, everything works fine. However, when I go down with
the sleep time below ~5 microseconds, things are getting weird.
The good news is that the problem
I concluded that this might be a solution. I tested it with 2.0.5 from
ubuntu repository. I had to add GC_allow_register_threads (and link
against gc, accordingly), because otherwise the program aborted with
the message "Threads explicit registering is not previously enabled"
whenever it attempted

I've recently noticed that the module loading process in Guile is not
thread safe. I hope to fi
