No, I do not have write access to gcc SVN. Just a part of technical staff at
our institute working to ensure portability of our scientific models. If patch
is OK(still think whole loop could be rewritten for better readability, but
runtime libraries tend to be tricky) could we expect fix backported to GCC7
branch?
Thanks in advance.
