Talk about silly byte-shaving ... the "stock" value of STACK_MIN_SIZE
|
|
does not work on s390x, and probably not on some other platforms either.
|
|
Knock it up to twice the pre-5.0.33 value to have some margin for future
|
|
changes in compiler, glibc, etc. Suspect this number if
|
|
"execution_constants" regression test fails.
|
|
|
|
As of 5.0.45 and F9, it seems 16384 isn't enough anymore either (ppc fails,
|
|
and seems to now need something above 24576 --- why?). STACK_MIN_SIZE has
|
|
to be enough less than DEFAULT_THREAD_STACK / 8 to provide some headroom,
|
|
which means we are now also forced to raise DEFAULT_THREAD_STACK for 32-bit
|
|
arches.
