Re: [Patch, fortran] PR55901 - [OOP] type is (character(len=*)) misinterpreted as array - part 1

[Paul Richard Thomas <paul dot richard dot thomas at gmail dot com>]

Dear All,

Steve Kargl has pointed out to me that the attachment was a null
attachment. As is well known, these are the Swiss Army knife of
patches and  will fix anything. In fact, this patch was already posted
long while since with the PR. However, since I am now in a slightly
more pedestrian mood, I have attached it to this message too :-)

Cheers

Paul
