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.
|
|
|
|
Note: STACK_MIN_SIZE has to be enough less than DEFAULT_THREAD_STACK / 8
|
|
to provide some headroom, which means that its value can't be raised too much
|
|
further without increasing the latter as well.

Feel free to raise this by the smallest amount you can to get the

"execution_constants" test to pass.
