If a process is sent a SIGURG signal and it is blocking SIGURG
signals, when the process subsequently unblocks SIGURG signals it will
be terminated even if it is set to the default action (SIG_DFL) which
is specified by SUSv3 to ignore that signal.
The following patch fixes the problem:

+++ linux-2.4.18/arch/i386/kernel/signal.c Thu Apr 18 12:19:37 2002

continue;
switch (signr) {
- case SIGCONT: case SIGCHLD: case SIGWINCH:
+ case SIGCONT: case SIGCHLD: case SIGWINCH: case SIGURG:
continue;
case SIGTSTP: case SIGTTIN: case SIGTTOU:
A quick browse of the other architectures indicates that most (if not
all) of them also need the same fix applied to their arch specific
signal.c files.

Christopher,
Could you please fixup (and test ;)) and other archs too ?

Looks like a correct fix to me. I made this change to the ia64 tree.
Thanks,
