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.
