New description:
When Sage encounters a SIGSEGV, it uses the glibc backtrace. This is
sometimes seen in doctests that are not reproducible, making it hard to
debug. The aim of this ticket is to return better automatic stack traces
by automatically attaching gdb and running scripts in gdb's Python
interpreter. This will will pinpoint the cause much easier, especially in
a debug build.
The log is printed to stdout and automatically saved to a log file in
`$DOT_SAGE/crash_logs` with logs older than a week automatically deleted.
A sample log is [attachment:sage_crash_wKcUKj.log]
Apply
* [attachment:trac_13889_enhanced_backtrace.patch] and
[attachment:13889_sagelib_review.patch] to Sage library
* [attachment:trac_13889_crime_scene_inspector.patch] to the
`$SAGE_LOCAL/bin` repo
