I came across a strange behavior with Gambit Scheme on Windows (XP, in this case). I wrote a module to convert C++ std::string types to Gambit char-strings. I wanted to use that in a loadable module. This all works fine on Linux, but I also need to use it on Windows. I'm using MinGW's C++ compiler (g++ version 4.6.2 -- which I also used to compile Gambit). And I'm still on version 4.6.5 of Gambit Scheme.
I've attached a zipped tar file with an example (6 files, including a build.windows script and a build.linux script).
When I load the shared module in gsi on Windows XP, it segfaults in ___garbage_collect(long) -- I believe it was in the call to ___alloc_scmobj. When I load it on Linux it works just fine. The executable built by the scripts on both platforms works just fine.
I would love to know what is causing this. I've spent many hours trying to find the source of the problem, and finally narrowed it down to this.
Any help/explanations/suggestions would be much appreciated.
