Strange.  At least for my (--enable-dbgutil) master build, following the 
instructions of fdo#46340 *does* lead to a restart with crash dialog and 
document recovery.

Also, experimenting with the attached crash.patch (see also 
<https://issues.apache.org/ooo/show_bug.cgi?id=108411> "let SID_CRASH 
really crash") does lead to the crash dialog in all four variations of 
the code (std::abort() vs. throw std::bad_alloc() and directly from main 
thread vs. pthread_create).
