Summary: r'\10' as replacement pattern loops in compilation

Initial Comment:
The following program loops under at least Solaris 9
on SPARC and Linux (kernel 2.6) in x86.  From
tracebacks, it seems to be in the internal compilation
of the pattern r'\10'.

from re import compile

line = ""

pat = compile(12 * r'(\d+)')

ltarget = float(pat.sub(r'\10',line))

print ltarget
