I am doing a test build of eglibc with commit 7e2fca8dd22e3bd932581d6479b0c552deff00b6 applied to see if it helps.
The commit is: commit 7e2fca8dd22e3bd932581d6479b0c552deff00b6 Author: Alan Modra <[email protected]> Date: Tue Sep 25 16:30:06 2012 -0500 Fix bugs in powerpc pthread_once. Ref gcc.gnu.org/bugzilla/show_bug.cgi?id=52839#c10 Release barriers are needed to ensure that any memory written by init_routine is seen by other threads before *once_control changes. In the case of clear_once_control we need to flush any partially written state. Reading the gcc bug report makes it sound like this only really triggers on a power7 system, which happens to be what I am using. I will let you know if this commit (which applies cleanly except for the changelog, with a one line offset) solves the problem. -- Len Sorensen -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
