It looks like Guile also uses the BoehmGC (although I don't know). We haven't
tried combining different versions of BoehmGC in the same process like this.
I expect that this is the cause of your problems.
I'm sorry to say that you're pretty much on your own here, we haven't faced
these problems before and can't really help. However, the following
information might be useful:
+ Mercury's version of BoehmGC is slightly modified, so replacing it with
guile's version of BoehmGC may not be easy.
+ Mercury and Guile may also use different compilation options for BoehmGC.
However this is just my speculation.
All the best.
