[Valgrind-users] using --gdb-attach=yes

[Timothee B. <tt...@id...>]

I am trying to use the --gdb-attach=yes option to use gdb and lookup
errors reported by valgrind. I am seeing the prompt:

==4853== ---- Attach to GDB ? --- [Return/N/n/Y/y/C/c] ---- ==4853==

But valgrind continues to run without actually stopping at the prompt.
What is causing this?

I don't think I'm doing anything really strange to stdin. It's a console
application with a little shell though, so I'm constantly scanning stdin
for my own input. I suppose that can be a problem?
