Not sure why you can't reproduce the failures, it's perfectly
reproducible for me. For the record, I'm doing this:
./configure --prefix=/home/user/pg-jsonpath --enable-debug
--enable-cassert CFLAGS="-O0 -DRANDOMIZE_ALLOCATED_MEMORY" && make -s
clean && make -s -j4 && make check
After sticking Assert(false) to JsonEncodeJsonbValue (to the default
case), I get a failure like this:
select json '{}' @* 'lax $[0]';
! WARNING: unknown jsonb value type: 20938064
! server closed the connection unexpectedly
! This probably means the server terminated abnormally
! before or while processing the request.
! connection to server was lost
The backtrace is attached. My guess is JsonValueListGetList in
jsonb_jsonpath_query only does shallow copy instead of copying the
pieces into funcctx->multi_call_memory_ctx, so it gets corrupted on
subsequent calls.
I also attach valgrind report, but I suppose the reported issues are a
consequence of the same bug.
