I"m running NetBSD/amd64 3.99.3 here.  I took an i386 hard drive and
did a complete, fresh install of -current a little while back, and have
not updated it since then.

In /usr/pkgsrc/lang/erlang, I was trying to build it.  I was told by
others that it does not really require Java, so I tried commenting
out the java-vm requirement in the Makefile.

During configure it hangs up on this line:

checking for unreliable floating point execptions...


...I let it run for over 8 minutes and it never finished this test.
I looked at the code it was running for it, and I couldn't see any
loops in the .c file.  It was chewing up all of the CPU.  (top(1)
actually said 101% to 102% of the CPU, but we'll leave that alone
for now.  (^&)

Can someone confirm?  Or would this likely go away if I updated
my kernel and/or the compiler & libraries?

I'm a little fatigued at this point, so I'm not going to fiddle
more with this for now to try to isolate just what's walking off
into limbo, and am just wondering if anyone else can reproduce it.
