The bugs in #10034 and #9791 only occur in the heavily optimized release binaries. I couldn't replicate them locally with threaded release (and didn't want to wait 40 minutes on fat linking).
But, I did found UB in a debug build while reading the json values. This is fixed in simd-lite/simd-json#301
