Description kevin 2004-03-19 10:23:41 UTC 
updated to glibc-2.3.2-r9. using LinuxThreads (NOT NPTL). ran gdb on an app with several threads. the app received SIG32 (SIGRTMIN). if gdb is told to ignore SIG32 (handle SIG32 nostop noprint pass) then a SIGTRAP is received and gdb can't see any threads anymore.

similarly, if a mutlithreaded app is running and gdb is attached to the process, it can't see any threads.

the app was compiled with debug info (-g3) and no optimizations.

downgrading to glibc-2.3.2-r3 caused this problem to go away.

no response.  Old version.  Closing.
