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

there is also mentioned strace :
$ strace -p PID

$ strace -p PID -t

other 'tools' for debug and tracing:
- valgrind

gcc personality problems

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

undefined reference to `__gxx_personality_v0'

one has to rely on the "personality" of g++ to keep the intergrity of the gcc self-esteem.
