Hi all,

This is an updated version of the patch I posted yesterday.
It fails silently rather than throwing if the executable is
not in the sysroot, which both fixes the sysroot-escape issue
and results in a better GDB session for the user.

Built and regtested on RHEL 6.6 x86_64.

Luis, I think this patch will fix your connection drop without
any further changes.  Could you test it please?

Unfortunately it doesn't completely solve the problem i saw, as
exec_file_find will still potentially throw errors and will disrupt the connection attempt or stop execution of a custom sequence of commands (as Pedro noted) when "attach" is part of the sequence.

define foo
attach <pid>
>>>> execution stops here if an error is thrown
info threads
info registers
end

It still looks like a TRY/CATCH block is needed around at least exec_file_find.
