[Fluxus] Fluxus crash in base.c

[mikhail lozanov]

Hello list,

I'm getting very strange crash when fluxus is starting. After some debugging it appears that scheme is crashing when trying to interpret data array defined in src/base.c

I'm running Lion 10.7.2 and fluxus is compiled in 32 bit. Racket is 5.2.0.1

Crash is because of access of null pointer in scheme environment, env->modules is null. Stack frame below is somewhat misleading but after debugging with Xcode attached to fluxus executable I localised that it's in scheme_apply(eload, 3, a);

Do somebody have a clue about this?

Thank you very much!
