I can pick up that patch.

Static functions having only one call site are especially vulnerable to
inlining, so avoid naming them in the suppressions file. I do see
ReorderBufferSerializeChange() inlined away at -O2 and higher. Is it fair to
tie the suppression to ReorderBufferSerializeTXN() instead?

Do you happen to have a self-contained procedure for causing the server to
reach the code in question?
