Looks like there is a problem with the faust plugins, originating from LLVM possibly.

Try moving the file out of the directory it is in and then trying to load it again.

Looks like LLVM is not exactly re-entrant then.

I was just looking at the code, and at opcode dlib loading time (when this seems to be crashing) there
is nothing specifically happening in terms of LLVM initialisation in Csound. All Csound does is look
for the dlib entry point to add the opcode to the list in Csound. Any explicit initialisation etc only happens
when Csound runs an orchestra containing the opcodes.

There must be something else happening in llvm (or libfaust).
