I have two computers, one with FreeBSD 11.0-RELEASE-p1 (amd64) , and a laptop with 10.3-RELEASE FreeBSD 10.3-RELEASE (i386) Also, I tried to use -lthr, -lpthread and -pthread, but it seems that the r= eal implementation underneath is libthr. I'm willing to give a hand if it's necessary. After some testing I can conclude: - GDB 6.6 works without problem, although it's using libthread_db.so to man= age threads. - GDB 7.x it's using a different implementation, and it's no longer using libthread_db.so, but using ptrace directly (specially after the last additi= on for LWP events). - Initially I discarded problems in the kernel, because GDB 6.6 was working, but now that I realized that they use different paths I'm not sure, maybe t= he new LWP code is broken. - I tried vanillas GDB from elsewhere, same exact problem. If I can help in anyway just let me know. Cheers, Javi. --=20 You are receiving this mail because: You are the assignee for the bug.=
