[Patch, fortran] PR29284 - [4.1/4.2 Regression] ICE for optional subroutine argument

[Rob]

Hi,

Will a possible fix to this problem be merged into
the 4.1.2 prerelease anytime soon?
I'm keeping in sync with this prerelease through
svn and I'll test it out once it's there.

Thanks for the quick response to my report on this
issue.

Rob.
