How to prevent gdb to send Interrupt signals to child processes

Hi,

I have a program which invokes child processes and communicates with the processes. When I run the program under gdb and say interrupt, all the child processes are dying. Here I am not interested in debugging the child processes. But I don't want my child processes to be killed as my parent process dies as soon as the child process is killed. Also I have no access to the child process code for any modifications. My assumption is that gdb sends interrupt signals to child processes because of which they are dying (but I am not sure about this).

I have tried "handle sigint nopass" on gdb. But it did not work for me.Please let me know if there is any way to prevent gdb to send interrupt signals to child processes.

Thanks in advance,
klnarayana

RUNLIM(1)						      General Commands Manual							 RUNLIM(1)

NAME
runlim - a program to run benchmarks SYNOPSIS
runlim [ options ...] command [ arguments ...] DESCRIPTION
run is a tool that can be used to run and control benchmarks. It executes a given command with (optional) arguments, samples resource usage during the run, and kills the process (and its child processes) if a certain time and/or space limit is exhausted. Every 100 milliseconds, runlim takes a sample of the program's resource utilization, and logs status information to stderr every second. Optionally, the status can be logged to a file. Multi-threaded programs can be limited by setting a wall clock timeout. runlim follows the time accumulation scheme of GNU time for multi- threaded programs and programs that spawn multiple child-processes: time spent in each thread/child is summed up, unless you are only interested in walk clock time. OPTIONS
runlim accepts the following options: -h, --help Show summary of options. --version Show version of program. -o FILE, --output-file=FILE Overwrite or create FILE for output logging. -s NUM, --space-limit=NUM Set space limit to NUM megabytes. -t NUM, --time-limit=NUM Set time limit to NUM seconds. -r NUM, --real-time-limit=NUM Set real time limit to NUM seconds. -k, --kill Propagate signals. SEE ALSO
time(1), timelimit(1), timeout(1), time(7). AUTHOR
runlim was written by Armin Biere and Toni Jussila. This manual page was written by Thomas Krennwallner <tkren@kr.tuwien.ac.at>, for the Debian project (and may be used by others). February 11, 2011 RUNLIM(1)
