Message361696
You can find the rationale for this change in two issues:
* bpo-27987
* bpo-36618
First, it was a warning in clang ubsan (Undefined Behavior Sanitizer).
Then ctypes started to crash when Python was compiled with clang. It
means that compiling Python 3.7 with clang also had the issue.
The quick fix was to compile Python with -fmax-type-align=8 when clang
was detected.
But it was a signal that something was wrong in Python on x86-64:
Python didn't respect the x86-64 ABI. |
