Description
When I checkout the latest version of SOMpp, it passes the test suite, but crashes on the Json benchmark. The gdb backtrace looks as follows:
(gdb) run -cp core-lib/Smalltalk/ core-lib/Examples/Benchmarks/Json/Json.som
Starting program: /home/ltratt/SOMpp/SOM++ -cp core-lib/Smalltalk/ core-lib/Examples/Benchmarks/Json/Json.som
This is SOM++

This is on Debian 4.19.118-2+deb10u1 x86_64 in case that's useful. It might be that I'm doing something stupid in the invocation of the benchmark, but I think this used to work?
