Thank you, it tindeed urns out to be a case of compiler flags. The problem only occurs
 whencompiling with gcc-8.2.0 with -Os -O2 (-ggdb is not relevant)
Apparently there is  jsc code which gcc miscompiles
when it is supplied with -Os -O2 and the crash smashes the stack 
so that there is no information in gdb.  I was alerted to the problem by a  similar unexpected 
crash in other software in a specific case, and possibly the  gcc bug can be tracked down.

I didn't bother to recompile without -Os on gcc-8.2.0 but am trying out clang instead
