The most likely cause is the dreaded pthread issue: the main
executable must be compiled/linked with -pthread (note: this is
not the same as -lpthread!). Otherwise a shared library which is
loaded later on and uses threads may cause a crash.
The easiest way to test this hypothesis is to rebuild LuaJIT with:
make TARGET_FLAGS=-pthread
... and then try again.
