Run 'make menuselect' and in the Compiler Options, enable MALLOC_DEBUG + and DONT_OPTIMIZE. A bug marshal may also ask you to enable additional + compiler flags, such as DEBUG_THREADS, depending upon the nature of the + issue. + +2. Rebuild and install Asterisk. + +3. Run Asterisk as follows: + valgrind --log-file-exactly=valgrind.txt asterisk -vvvvcg 2>malloc_debug.txt + + UPDATE: The newest version of valgrind has eliminated the + --log-file-exactly option. If you are running valgrind 3.3.0 or higher, + just use the --log-file option, keeping in mind that Valgrind will append + a trailing suffix onto valgrind.txt. + +4. Reproduce the issue. Following the manifestation of the issue (or when + the process crashes), upload the two files, valgrind.txt and + malloc_debug.txt to the issue tracker. If you are using the --log-file + option, note that valgrind.txt will have a trailing suffix. That's fine, + just upload that file. + +Please note that even if valgrind prevents Asterisk from crashing, the +information logged may STILL be of use to developers, so please upload the +resulting log file whether Asterisk crashes or not. + |
