[issue24999] Segfault in test_re.test_sre_character_class_literals() when Python is compiled by ICC

[STINNER Victor]

New submission from STINNER Victor:

The crash occurred on the buildbot "x86-64 Windows Server 2012R2 ICC 3.x".

Do you we officially support the ICC compiler?

There are still some curious compiler warnings:

Objects\longobject.c(4498): warning #63: shift count is too large
=> "#if LONG_MAX >> 2*PyLong_SHIFT"
Objects\longobject.c(4519): warning #63: shift count is too large
=> "#if LONG_MAX >> 2*PyLong_SHIFT"

I don't understand the test: do we test if the result is zero?

On Windows, a long is only 32-bits. I guess that PyLong_SHIFT is 30 (so 2*PyLong_SHIFT=60).

Maybe we should put "#elif defined(PY_LONG_LONG) && PY_LLONG_MAX >> 2*PyLong_SHIFT" before?
