How to temporarily disable gc?

[Richard Guenther]

Hi!

I (probably) neet to disable gc temporarily, how can I do this?
Using gh_defer_ints(); ... gh_allow_ints(); doesnt do the trick.
I think gc is somehow causing the following SIGSEGV:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1024 (LWP 16068)]
0x40108a4c in scm_igc () from /usr/lib/libguile.so.9

(gdb)

Note, that fft_resample.scm will fail if executed, i.e. it raises
(SCM_ASSERT()) an exception. The catch handler installed is just a
NOP, but it isnt even reached it seems.
