For whitespace errors, see the file /Users/mabshoff/sage-3.1.2.alpha3/tmp/.doctest_matrix_mod2_dense.pym4ri_mm_calloc: calloc returned NULL

A mysterious error (perphaps a memory error?) occurred, which may have crashed doctest.

comment:1

The doctest failures can easily be fixed by disabling the respective code (it is just there for testing purposes and that code isn't used by anything in production use yet)

I'll have to come up with a second patch for the CALLOC issue.

comment:2

Patch looks good to me. The calloc issue might or might not be solved by the new upstream spkg. If it is still a problem I will open a new ticket for it.

Cheers,

Michael

comment:3

A new SPKG is up at:

http://sage.math.washington.edu/home/malb/spkgs/libm4ri-20080901.spkg

With that SPKG and a touch on matrix_mod2_dense.pxd + sage -b all tests pass on BSD:

Sage subshell$ sage -t ~/sage-3.1.2.alpha3/devel/sage/sage/matrix/matrix_mod2_dense.pyx
sage -t  devel/sage/sage/matrix/matrix_mod2_dense.pyx
         [4.4 s]

----------------------------------------------------------------------
All tests passed!
Total time for all tests: 4.4 seconds

The spkg has been reviewed at #4024, so I am giving the patch a positive review since it makes the doctest work on OSX 32 bit again.

Cheers,

Michael
