Ok, it seems you diagnosed it pretty quickly, great!

Oops! I forgot about this. I'll switch to -S.

Right, thank you for the suggestion.

If I think again, this might explain some previous weird behaviours that I 
experimented a while ago.

For production tests I do not use the gdb server configuration, and semihosting 
was functional even with two options.

So yes, it was good fortune.

If you fix the bug, could you notify me when ready, to make a new xPack release?


Thank you,
