Reporter: richard at netbsd dot org
Running the testsuite for gcc 4.9.1 I notice the following gfortran failures:

Concerning the fmt_g0_1.f08 cases, I notice in particular that while debugging
the following bits are the problem:
10 write(buffer, string) ':',1.0_8/3.0_8,':' │
11 if (buffer.ne.":.33333333333333331:") call abort │
after 10, the value of buffer is:
(gdb) print buffer
$1 = ':.', '3' <repeats 16 times>, '2:', ' ' <repeats 30 times>
Testsuite problem or no?
This is running on SunOS 5.11 (illumos) pkgsrc trunk
