[Pkg-mc-devel] Bug#666275: mc: crash when deleting a file with MALLOC_CHECK_, MALLOC_PERTURB_ on

Package: mc
Version: 3:4.8.1-3
Severity: normal
Usertags: malloc
While trying to delete a file using mc I got a random crash. I expect
this is because I set MALLOC_CHECK_ and MALLOC_PERTURB_, which turn on
heap consistency checks that help find memory allocation bugs. If the
below backtrace is not useful, please close this bug.
