gcc-4.6.2 -march=amdfam10 -O3 (-m64)

The terminal is irrelevant.  It spins even with set term dumb.

Removing a single 9 from 0.99999999999999989 is enough to make it work.

The hang is in gen_tics().

When I interupted the gdb session, it was in gen_tics() at the gprintf()
call on line 1173, just before the /* Range-limited tic placement */
comment.  It reduces to:

  gprintf("1.00000000000000", 50, "%.14f", 1.0, 1);

at the gen_tics() level, but gdb says the format is just "f" when I'm at
the gprintf() level....

It must loop somewhere therein.
