Mtrace with no environment MALLOC_TRACE feature request mtrace_setpath.

Request for mtrace_setpath


In debugging and profiling PAM (Pluggable Authentication Modules) modules for memory leaks in linux, mtrace cannot access environment variables as these do not exist until the authentication completes (e.g. /etc/environment . The MALLOC_TRACE path can only be supplied as an environment variable. Please add a feature to allow the passing of a trace path to mtrace. The module workaround is to add putenv("MALLOC_TRACE=/var/log/mypammemleak.log");


Globally changing the linux environment values to trace a security module should not be an answer.


Please consider adding a mtrace_setpath(const char* path);


Note : pam_env.so creates environment variables afterward. I've checked everything other than rebuilding PAM.

Module order does not matter.
