This library created a service thread that it needs to terminate when dlclose is called. But if the service thread takes an exception after the call to dlclose and the libraries call to pthread_join then the service thread will hang in the unwind code and the join will never complete. -- Summary: Deadlock between dlclose and c++ exception/unwind Product: glibc Version: unspecified Status: NEW Severity: critical Priority: P1 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: sjmunroe at us dot ibm dot com CC: glibc-bugs at sources dot redhat dot com GCC build triplet: powerpc-linux GCC host triplet: powerpc64-linux GCC target triplet: powerpc-linux http://sourceware.org/bugzilla/show_bug.cgi?id=2377 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
