[New-bugs-announce] [issue16050] ctypes: callback from C++ to Python fails with Illegal Instruction call

[Pavel Maltsev]

New submission from Pavel Maltsev:

ppc_405, Linux 2.4, GCC 3.3.1

Python crashes on attempt to pass python callback function to custom C++ library under PowerPC 405. This happens because some versions of GCC (I guess below 4.1) doesn't raise __NO_FPRS__ flag if hard-floats is not supported, instead they use _SOFT_FLOAT. So we need to change

#ifndef __NO_FPRS__
to
#if (!defined(__NO_FPRS__) && !defined(_SOFT_FLOAT))
