ctypes pretends to support passing arguments to C functions that are structures containing bitfields, or at least does not explicitly forbid it. But doing so results in misbehavior or segfaults in libffi itself. Indeed, libffi has no support for this, and ctypes just describes a field like "int x:1;" as "int x;". The attached example segfaults on Linux x86-64. |

The same misbehavior occurs if the structures are packed ("_pack_ = 1"). Attached in test186_lib.tgz.

I propose to start with the attached documentation fix (generated vs. 3.2 but should be applied to all active branches). A code fix has to be discussed more thoroughly because in theory some code running only on x86-32 can rely on it and will break. |
