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.
Does the follow
FWIW, I couldn't reproduce this problem on my system (i.e. str_test
always printed "1"). GHC 6.2.1, libgmp 4.1.3, debian unstable

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

Hi,
please be aware that the RTS uses GMP as well, and upon
initialisation it sets GMP's 'memory functions' to allocate memory
from the RTS' heap. So, in the code below, the global variable
'p' will end up having components pointing into the heap.
Which is fine, until a GC occurs and the pointed-t
19 matches
