Talk about silly byte-shaving ... the "stock" value 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 (ppc fails).
|
|
But we can't raise it too much because it has to be less than
|
|
DEFAULT_THREAD_STACK / 8, and DEFAULT_THREAD_STACK is dependent on
|
|
SIZEOF_CHARP. (Could change DEFAULT_THREAD_STACK too if our backs are
|
|
to the wall, but I'd rather not.)

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

"execution_constants" test to pass.
