Yes, I am using gdbserver. Right now SIGALRM is treated as pass noprint
nostop. Would you have more details on how to do this hack? ;)

Unfortunately not, it can happen in normal methods. I am compiling
with -g and without any optimisation option.

after the class names (Class::<tab> produces nothing), I suppose I am
missing a little something?
