Hi Maciej The minimal program is as below: nt main() { rpython_startup_code(); pypy_init_threads(); pypy_setup_home(...); pypy_execute_source_ptr("print \'hello\'"); } It hangs in pypy_execute_source(). And if we remove "pypy_init_threads()", the code works. With gdb debug, it blocked at this stack: #0 0x0000003fea40b1c0 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007ffff6369305 in RPyGilAcquire () from .//../dist/libpypy-c.so #2 0x00007ffff55bb8ed in pypy_g_pypy_execute_source_ptr () from .//../dist/libpypy-c.so #3 0x00007ffff53a8f42 in pypy_execute_source_ptr () from .//../dist/libpypy-c.so #4 0x00007ffff53a8d82 in pypy_execute_source () from .//../dist/libpypy-c.so #5 0x0000000000400b2e in main () at udf_call_test.c:84 The alternative method is we might add a finialze() method to clear all enviroment, and another thread could initialize again.

do you have a minimal example where it doesn't work? did you try a very minimal program?

Hi Armin,
Sorry for I didn't describe the problem clearly. The issue is well reproducible with the belolw simple piece of the code:
#include ...
int main() { rpython_startup_code(); pypy_init_threads(); pypy_setup_home(...); pypy_execute_source_ptr("print \'hello\'"); }
It hangs in pypy_execute_source(). And if we remove "pypy_init_threads()", the code works.

I tried the following in one thread, and it hang in pypy_execute_source_ptr(). * rpython_startup_code(); * pypy_init_threads(); * pypy_setup_home(...) * pypy_execute_source_ptr()
I meant "do whatever you did so far here". I can't debug a new problem you get if I only know "it hangs"...
A bientôt,
Armin.
