Re: Memory allocation error in lpeg v0.9

Wow ! It worked.
Can I ask how I was suppose to know something like that? Is it a well
known bug/trick/idiom for building things on Mac OS X? I think I will
try to do the same with the other Lua libraries I built.

Very much thanks anyway. I hope this will help other non C programers
and/or compilation gurus or whatever like me.
