Not really. You can't let GMP realloc() a memory block that was
allocated using one method, with

Nah, easy.
First get a list of symbols: nm libgmp.a | grep gmp
[Supply a few flags to nm to get a better list.]
Then turn it into a list of #defines:
#define gmp_blah ghc_gmp_blah
...
#include your list of #defines into

Show us the code! :-p

Ah, that triggers the bug for me as well. Oddly, calling
System.Mem.performGC once isn't enough, but twice is:
Ok, modules loaded: Main.
*Main> mpz_new
*Main> System.Mem.performGC
*Main> str_test
1
vs.
Ok, modules loaded: Main.

Same versions here, on an old heavily-patched/FUBAR rock linux
1.4 system.

What about linking Haskell programs with C libraries that use GMP
internally

Hi all,
I recently tried to create a ffi-binding to gmp in ghc, and
failed miserably. After a few days of debugging, simplifying the
code and tearing my hear out, I'm slightly completely stumped,
and crying for help ;)
In short: calling gmp-functions from GHCI *with a prompt between*
