Package: gdb Version: 7.4.1-3 Severity: normal Tags: patch Dear Maintainer,
I noticed that when debugging threaded programs on debian-kfreebsd-amd64, gdb would sometimes hang after a LinuxThreads signal was supposed to be delivered. I believe the attached patch improves things, though it is still not ideal because it is not possible to direct gdb not to stop or print these two signals. -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: kfreebsd-amd64 (x86_64) Kernel: kFreeBSD 9.0-2-amd64 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gdb depends on: ii libc0.1 2.13-37 ii libexpat1 2.1.0-1 ii libkvm0 9.0+ds1-4 ii libncurses5 5.9-10 ii libpython2.7 2.7.3~rc2-2.1 ii libreadline6 6.2-8 ii libtinfo5 5.9-10 ii zlib1g 1:1.2.7.dfsg-13 gdb recommends no packages.
