libtcc contains some global state, i.e. shared between TCCState objects
you create. Some of this sharing is harmless, some of it isn't; the
latter is the reason why two compile objects generally don't work except
by accident. Fixing this implies adding one indirection, and some of that
state is used in extremely performance critical code, so it has never been
a priority.
So, yeah, it's a current limitation of libtcc.
Ciao,
Michael.
