            Bug ID: 63352
           Summary: problem with fmt_g0_1.f08  on i386-pc-solaris2.11
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: richard at netbsd dot org

Running the testsuite for gcc 4.9.1 I notice the following gfortran failures:
        === gfortran tests ===

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?
