I recently fixed a misaligned memory bug that showed up on SPARC 64-bit.
I think it was also a "bus error". The patch was in the
pcre2_serialize.c file, but I cannot remember whether the fix was before
or after the -RC1 tarball was made. The bug was not related to JIT, but
I think there are still JIT issues with SPARC 64-bit, aren't there?
Could this be related?
