You mean local builds? Unless you have ac_add_options --enable-debug in your mozconfig you won't see stack traces. What you can do in that case is build with the crash reporter enabled and point the MINIDUMP_STACKWALK env variable to a build of the stackwalker. When you'll hit an assertion a minidump will be generated, the test harness will detect it and print out a stack-trace by feeding it into the stack walker. Not optimal but better than nothing. All of the above already happens on automation when running tests for optimized builds: you won't have inline stack traces for crashes but at the end of the test you'll see the crash dump with the complete stack trace.
