ddd stops program because of signal SIGINT

[Bonnie Wu]

Hello:

I am using ddd (3.2.98) on RedHat linux.

When I use ddd to laugh a multithread program, ddd stops because of
"Program received signal SIGINT, Interrupt.
[Switching to Thread 27145]
0x415ab58b in __sigsuspend (set=0xbc7ffab0) at
/opt/sysdeps/unix/sysv/linux/sigsuspend.c:48"

I press "continue" button. The same message appears many times until it
gets the following message.

"Program received signal SIGINT, Interrupt.
[Switching to Thread 27135]
0x4163ddf2 in __libc_recv () from /lib/libc.so.6"

Finally, the program can not work properly.

I am running the same program on my colleague's ddd environment, none of
the above messages appear. He didn't have /opt/sysdeps even.

Would you mind letting me know how to fix that problem if you have the
same experience before?

Thanks in advance,

Bonnie
