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

[Stefan Krah]

Stefan Krah added the comment:

Yes, according to C99 the shift is undefined:

6.5.7:

"If the value of the right operand is negative or is greater than
 or equal to the width of the promoted left operand, the behavior
 is undefined."
