The 22.locale.messages test hangs SUSE LINUX Enterprise Server 9
(x86_64). I reproduced the problem in a 15D build with gcc and in
a 12D build with Sun C++ on the same machine. Based on the stack
trace it looks like the test tries to throw an exception whose
what() string is then attempted to be formatted by the library
by using a messages facet. Since all message facets share the
same mutex the library deadlocks.
I wonder if this might be the cause of the problem:
http://svn.apache.org/viewvc?view=rev&revision=576787
In addition, the exec utility also seems to fail to kill the test
after the usual timeout and the test (and the rest of the build
process) hangs. The last change that went in to exec that looks
like a possible suspect is this:
http://svn.apache.org/viewvc?view=rev&revision=590124
(Farid, the ChangeLog has your name on it even though the change
itself was mine. Let it be a reminder to you to give blame where
blame is due :)
Here's the backtrace:
