gdb session with backtraces from throws and catches

I have reached a result very similar to Julien's in comment 3,
collecting backtraces from throw's and catch's along the way.  Some
line numbers:

    line  what
    ----  --------------------------------------------------------
     187  ready to adjust spacing; set catchpoints
     203  exception thrown
     267  exception caught
     328  exception thrown
     393  exception caught
     455  exception thrown
     521  exception caught
     584  exception thrown
     647  exception caught
     707  exception thrown
     791  exception caught
     875  exception thrown
     906  exception caught
     941  SIGSEGV

At the SIGSEGV, Julien and my backtraces show different functions in
frame #0; after that they show the same function names.

My observations are from a local build of commit 3a5d7836
(2019-04-09), configured:
    CC=ccache /usr/bin/gcc
    CXX=ccache /usr/bin/g++
    CCFLAGS=-Wshadow
    --with-jdk-home=/usr/lib/jvm/default-java
    --enable-split-debug
    --enable-gdb-index
    --enable-ld=gold
    --enable-option-checking=fatal
    #--enable-dbgutil
    --enable-debug
    --without-system-postgresql
    --without-myspell-dicts
    --with-extra-buildid
    --without-doxygen
    --with-external-tar=/home/terry/lo_hacking/git/src
    --without-package-format
built and running on debian-buster.

I am removing keyword wantBacktrace and adding haveBacktrace.
