It does fix this, but it's not clear to me what the most correct fix for this is. Other libthread_db targets in gdb for Solaris and Linux just avoid attaching to core dumps entirely. This patch makes the FreeBSD thread target throw away the threads enumerated by the default core dump target and re-enumerate them using the FreeBSD target directly. -- You are receiving this mail because: You are the assignee for the bug.
