Hmm. Looking at the 12.1-stable siginfo manpage this seems to be fixed

SIGBUS BUS_ADRALN invalid address alignment
BUS_ADRERR nonexistent physical address
BUS_OBJERR object-specific hardware error
BUS_OOMERR cannot alloc a page to map at fault

with this being added to signal.h

#define BUS_OOMERR 100 /* Non-standard: No memory. */

So presumably this will go away in 12.2.

A+
Paul
