-"""
-The regular expression engine in '_sre' can segfault when interpreting
-bogus bytecode.
-
-It is unclear whether this is a real bug or a "won't fix" case like
-bogus_code_obj.py, because it requires bytecode that is built by hand,
-as opposed to compiled by 're' from a string-source regexp. The
-difference with bogus_code_obj, though, is that the only existing regexp
-compiler is written in Python, so that the C code has no choice but
-accept arbitrary bytecode from Python-level.
-
-The test below builds and runs random bytecodes until 'match' crashes
-Python. I have not investigated why exactly segfaults occur nor how
-hard they would be to fix. Here are a few examples of 'code' that
-segfault for me:
-
- [21, 50814, 8, 29, 16]
- [21, 3967, 26, 10, 23, 54113]
- [29, 23, 0, 2, 5]
- [31, 64351, 0, 28, 3, 22281, 20, 4463, 9, 25, 59154, 15245, 2,
- 16343, 3, 11600, 24380, 10, 37556, 10, 31, 15, 31]
-
-Here is also a 'code' that triggers an infinite uninterruptible loop:
-
- [29, 1, 8, 21, 1, 43083, 6]
