[issue40244] AIX: build: _PyObject_GC_TRACK Asstertion failure

[Stefan Krah]

Stefan Krah <stefan at bytereef.org> added the comment:

Since I just had a similar incident with the Intel compiler, I just
want to point out that compiling CPython still requires -fwrapv.

I've mentioned this before in AIX issues, and no one has pointed
out the corresponding xlc flag.

"Dan Berlin says that xlc assumes signed overflow never occurs"
