hmm... ok... then we will need to adapt libfst to the new wine_init call,
to be prepared for the next release.
do you already know what #if i need ?

pthread_self() is broken in your case.
i have seen this behaviour in a signal handler with an alternate stack.
my pthread_implementation does not use thread local storage and
therefore pthread_self uses the stack to identify the thread.
newer glibc should be using %gs for this stuff.
but your %gs register is 0.
very strange.
can you check what the registers contain using breakpoints ?
gdb> info registers
it would be nice if you can find out with what options your glibc is
configured with.
this must be a glibc issue because its working for marek, who uses the
same glibc i do.
