Other similar test failures include multiple test cases in test_ipaddress, 
test_raise, and test_traceback, for example:

The same universal build runs without error on an Intel Mac with the same os 
version.  The ppc failures are seen on both PPC OS X 10.5 and 10.4 systems.

Ned Deily added the comment:

It appears similar failures are occuring on Sparc platforms (see issue15589) 
another big-endian platform.

[issue15597] exception __suppress_context__ test failures on OS X ppc systems

2012-08-08 Thread STINNER Victor 

STINNER Victor added the comment:

__suppress_context__ is a member using T_BOOL type. T_BOOL expects the C type 
char, whereas the field in the PyBaseExceptionObject is a C int. Attached 
patch changes the type and should fix the issue.

The test fails because writing into the field uses:

 *(char*)field = value;

Which does not work in big endian if the field is a pointer to an int.

[issue15597] exception __suppress_context__ test failures on OS X ppc systems

2012-08-08 Thread Ned Deily 

Ned Deily added the comment:

The patch does indeed fix all of the __suppress_context__ related test failures 
previously seen, i.e. test_exceptions, test_ipaddress, test_raise, and 
test_traceback.
