I seem to have missed the description of the "red-zone" when I read the ABI. It's a
neat optimization
for leaf functions, but violates the principal of least suprise.
I have confirmed that the MySQL4 crashes that we were experiencing went away with
-mno-red-zone.
I have done further investigation, and it appears that NetBSD/amd64's thread context
switch code did
not preserve the red-zone until recently. This has been fixed in -current, and
hopefully the changes
will be pulled up to the release branch before 2.0 is released.
