Comment(by m-paradox):

 Hmmm, it's hard to see what could be causing this crash, since the
 function it's crashing in is pretty straightforward. I've just committed a
 fix to one bug in the function, which I doubt was causing the crash but I
 could be wrong. There are two things you could do to help narrow down the
 cause further:

 - Get the gdb backtrace to include NumPy line numbers.  It has the
 symbols, but this would narrow things down better.  I suspect this
 requires compiling NumPy with some more debug options, but I'm not sure
 exactly what is needed.

 - Enable the printf tracing built into
 numpy/core/src/umath/ufunc_object.c.  Near the top, there is a section
 like this:

 {{{
 /********** PRINTF DEBUG TRACING **************/
 #define NPY_UF_DBG_TRACING 0

 #if NPY_UF_DBG_TRACING
 #define NPY_UF_DBG_PRINTF(...) printf(__VA_ARGS__)
 #else
 #define NPY_UF_DBG_PRINTF(...)
 #endif
 /**********************************************/
 }}}

 If you change the 0 to a 1, it will print out a lot of information about
 the ufunc evaluation while it's running, and this may provide some clues
 as to what's going wrong.
