(In reply to Mark Johnston from comment #1)

> madvise behaviour 25 is MADV_COLLAPSE.  From reading the description, it causes the kernel to try and map the specified range using superpages if possible.  I would expect that to be safe to ignore, the problem is something else.

OK, so FreeBSD does not abort, simple because it doesn't know this flag? Yeah,
then it's something else.

Is there a recommended way for debugging segfaults in the linux-compat?

> What has changed since "previously"?

Other/older games, so not relevant here (because those games likely just didn't
request the flag).
