https://bugzilla.redhat.com/show_bug.cgi?id=1470030 --- Comment #4 from Paul Howarth <paul@xxxxxxxxxxxx> --- (In reply to Mark Wielaard from comment #3) > It would be good to run the testcase by hand under valgrind with > glibc-debuginfo installed so we get precise source code lines in the > backtrace and using valgrind --track-origins=yes to see where exactly the > issue comes from.
