Our main development server was "upgraded" to 64 bits, but mostly still runs 32 bit software, so this is from a 32 bit build on a 64 bit platform. Naturally, this all works on 32 on 32 and on 64 on 64. But with 32 on 64, not so well:
I presume you are talking about Linux and going from i386 to amd64/x86_64 (not sure which name is used in Linux). I would be suspicious that the i386 binary is getting linked with some amd64 libs somehow - to first order it would seem to be an OS bug if the emulated i386 binary doesn't run the same as on i386. But I could certainly see an allowable difference leading to triggering a latent bug in guile. Can you trigger this with a simple example? I have i386 and now amd64 boxes, and would be curious to try the NetBSD i386 binary on amd64, as well as native.
