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.
