Hi,

The toolchain you used seems to support the non-PIC extensions to the ABI
for MIPS (used for the exe). I have not tested such binaries...

Can you for example try tracing the puts call?

I've also found a couple of issues with multithreading and the patch I
sent. Will post a fix tomorrow. (We need to add breakpoints to the
proc->leader which is not always done right now). That makes threaded
apps mostly work (allthough there are known races).

Cheers,
Edgar
