Bug#710439: Testing glibc commit 7e2fca8dd22e3bd932581d6479b0c552deff00b6 to see if it is the solution

["Lennart Sorensen" <lsorense@csclub.uwaterloo.ca>]

I am doing a test build of eglibc with commit
7e2fca8dd22e3bd932581d6479b0c552deff00b6 applied to see if it helps.

The commit is:

    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.
