Hi, with current svn I get a segfault for numpy.test(10, 10): check_manyways (numpy.lib.tests.test_arraysetops.test_aso)Segmentation fault There are no "incompatible pointer type" during the build of numpy. The backtrace is below. I hope this has not been reported during the last two days (I hardly manage to keep up with the traffic during the week ;-). Best, Arnd Program received signal SIGSEGV, Segmentation fault.
