Subject: embedding ruby - segfault after initialization when running rb_gc_start??

Hi, 

I'm trying to embed Ruby into the Ur web programming language.

Everything seems to work fine when using rb_gc_disable().
When not disabling gc it segfaults when requiring 'net/http'.

Then I tried running gc manually and found out that the crash even
happens after initialization.

However it only happens when urweb compiles everything. Compiling a
embed ruby into C test case everything is fine.

What could be causing this?

valgrind log, initialization code:
http://mawercer.de/~marc/crash.txt

Any ideas? Could symbol collisions cause this?
The libruby.so file is used. Ruby version is 1.9.2-p0

The strange thing is that the segfault only happens when being called
within urweb.
