The size of long double is also 12 under 32-bit Linux. Perhaps mingw disagrees with Visual Studio
Yes, mingw and VS do not have the same long double type. This has been the source of some problems in numpy as well, since mingw uses the MS runtime, and everything involving long double and the runtime is broken (printf, math library calls). I wish there was a way to disable this in mingw, but there isn't AFAIK.
on some ABI subtleties (is it expected? is mingw supposed to be ABI-compatible with Visual Studio? if yes, you may report a bug to them :-)).
I think mostly ABI compatible is the best description :)
Well, the source of my problems is simply that I tried to build an extension for a Visual Studio built Python, using mingw. Did that, because it seems to be common practice so far. Maybe the simple solution is to prevent building extensions with mingw, if the python executable was not also built with it? Then, all would be fine I guess. Despite the fact that Python probably has to be changed: If it is true then all the 32-bit Linux Pythons have a 12 byte GC head, IOW they are *all* badly aligned. If that matters, of course. cheers - chris -- Christian Tismer :^) <mailto:tismer@stackless.com> tismerysoft GmbH : Have a break!
