In fact, my trouble is that when things are compiled to native code, it

Are pthreads compatible with OCaml bytecode?
I believe so. Could you post some code and instructions how to build for
investigation?
I'm working on it. Will look at ocamlforge for this purpose.
I now think, however, that it's not a thread issue. MonetDB loads
dynamically at startup some other libraries for its own low-level
language, MAL (for MonetDB Assembly Language). I believe this kind of
dynamic loading works fine in native code, but doesn't in bytecode.
I've got no issues in native code at all... Only with bytecode.
Haven't located the place in MonetDB where this dynamic loading happens,
so it's just conjectures for now.
If someone knows how to use gdb on a bytecode executable to locate the
segfault in MonetDB's .so file, I'd be quite happy to know.
All the best,
