From badf6dd685a37f85be05720797cf675c4d58846c Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Sat, 29 Jan 2005 14:20:10 +0000 Subject: Hi Erik and Manuel Long time no see :) It appears uClibc pthreads native debugging is broken w.r.t thread exit handling in uClibc(at least on PPC). When debugging ex7, gdb(6.2.1) bails out as soon as a thread exits. I found a comment in gdb that TD_DEATH handling was broken for glibc 2.3.1, so I figured that maybe it was broken in uClibc also. I added a #if 0 #endif in pthread_exit( see patch below) and then gdb behaved again. While looking into this I found a few differences( included in the patch) between glibc and uClibc. Don't know if these makes a difference, but I leave that to you to decide.
