[Numpy-discussion] Numpy.test() hangs

Hmmm... So I examined an objdump of umath.so:
objdump -d /usr/lib/python2.5/site-packages/numpy/core/umath.so > umath.asm

The relevant lines are here:
---
00000000000292c0 <log1pf>:
   292c0:	e9 fb ff ff ff       	jmpq   292c0 <log1pf>
   292c5:	66 66 2e 0f 1f 84 00 	nopw   %cs:0x0(%rax,%rax,1)
   292cc:	00 00 00 00
---

Not sure if i'm reading this correctly, but the first line seems to be
an unconditional jump to itself, hence an infinite loop?
