(not sure why they're in 'T')

Comment 1 Jan Kratochvil 2006-10-05 19:26:00 UTC

It is already fixed in gdb-6.5-9.fc6 which will be present in RawHide after FC6
gets released. FC6 will contain "gdb-6.5-8.fc6". Bug is present even upstream.

'T' state looks as SIGSTOP from some SIGTTIN or SIGTTOU due to stty(1) not being
supplied proper console descriptor as fd 0.

Comment 4 Fedora Update System 2006-10-26 17:46:08 UTC

gdb-6.5-13.fc6 has been pushed for fc6, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
