Hello everybody,

I'm spawning GDB with g_spawn_async_with_pipes in IDE extension written in GTK,
and have a problem sending "-exec-interrupt" request to it via g_io_channel_write_chars.
When I'm trying to do so, parent IDE process receives SIGINT even if I set "signal(SIGINT, SIG_IGN)" right before
calling g_io_channel_write_chars.
If I send another command (-break-list for example) in the same situation -
no problem, so I suppose it's related somehow to the signals GDB sends to it's parent when
interrupting debugging process, but I'm confused about how to deal with it.
The stack trace is like that:
