SIG33 and the other POSIX RT (runtime) signals

Here is a tutorial about POSIX signals.

from an other source:
if you get "Program received signal SIG35, Real-time event 35.", this is due to a directory changing rather than a bug. You can disable these events and then c(ontinue) (the signal number may vary):

(gdb) handle SIG33 noprint nostop
(gdb) c

gcc - the c compiler - has a pretty funny error, when you try to compile a non c file with it:
