this is a regression compared to 2.5.2. Not seen on 2.6 or 3.0. Please
consider a fix before 2.5.3 is released.

Deferring until 3.0 final is out.

Thomas, do you have an idea what might be causing this problem, or a
proposal how to resolve it?

theller commented Dec 10, 2008

Is this really a regression? I do not think so; the libffi library
included with the Python 2.5 ctypes does not support closures on the
arm. See file Modules/_ctypes/libffi/src/arm/ffitarget.h, it contains
'#define FFI_CLOSURES 0'.

The question is whether it used to build in 2.5.2, but doesn't build
anymore now. If that's what happening, it is a regression.

It seems that ffi_info moved into ctypes.h: could that have caused the
breakage?

Not sure what you mean exactly (there is no ffi_info in ctypes.h), but I
assume you are referring to svn rev. 62504?

That's the revision I meant, yes. It seems that ffi_info just got
renamed, so I misread the change. In any case, it's (now) unclear how
this did compile before, as ffi_closure was always referenced in ctypes.h...

Unfortunately, the ARM buildbot is down right now, so no tests can be
performed.

As the ARM buildbot is still down, we have no way of analysing or fixing
this problem, so I'm closing this as "won't fix".
