* [BZ #22830] malloc_stats: restore cancellation for stderr correctly.Zack Weinberg2018-02-101-0/+216
malloc_stats means to disable cancellation for writes to stderr while it runs, but it restores stderr->_flags2 with |= instead of =, so what it actually does is disable cancellation on stderr permanently. [BZ #22830] * malloc/malloc.c (__malloc_stats): Restore stderr->_flags2 correctly. * malloc/tst-malloc-stats-cancellation.c: New test case. * malloc/Makefile: Add new test case.
