Once people have confirmed that, I will make it a 9.2 update.

Try a bt on each thread to confirm that each thread has its own context. I fixed this on my Mandrake 9.0 by recompiling glibc from the .srpm then copying the unstripped pthread libraries over the top of my existing pthread libraries which I had backed up first. After a quick reboot cos this was quick and dirty, gdb worked fine on my threaded apps. I notice that the spec file for the glibc srpm did not have the pthread libraries in the no strip section - that should be the only required change. -- Configure bugmail: http://qa.mandrakesoft.com/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. --- Reminder: --- assigned_to: [EMAIL PROTECTED] status: NEW creation_date: description: MythTV (http://www.mythtv.org) is a multi-threaded application.

Re: [Cooker] [Bug 5568] [gdb] gdb continuously stopping for SIG32 events
Hi, The nostop merely hides the issue and causes problems later on. This severely impacts the ability to debug the multi-threaded application. The fix first implies to fix rpm then rebuild glibc. A workaround would be to manually handle EXCLUDE_FROM_STRIP stuff -debuginfo generation from within glibc package. In either case, this is an 9.2 update candidate. Bye, Gwenole.

It is not a bug per se. This sets gdb to ignore it : handle SIG32 nostop noprint pass BTW, are you seeing also SIGTRAPs ? That is more interesting, since it breaks debugging of multi-threaded applications for me completely. I described the problems I have got here : http://qa.mandrakesoft.com/show_bug.cgi?id=4709 Usually I get SIG32, then set it to nostop,noprint, pass and immediately get SIGTRAP after typing continue.
