Try storing the following in a .gdbinit file in your current directory:

set print sevenbit off
handle SIGUSR1 nostop noprint
handle SIGUSR2 nostop noprint
handle SIGWAITING nostop noprint
handle SIGLWP nostop noprint
handle SIGPIPE nostop
handle SIGALRM nostop
handle SIGHUP nostop
handle SIGTERM nostop noprint

It should fix all the automatic signals you get from gdb.

Note that MySQL needs SIGALRM to work;  Are you modifying this in
Innobase in any way?
