Close PR - won't fix for 4.3 to 4.5, FIXED for 4.6.
Reasoning for closing the PR without backporting:
- Not backported so far
- Rather large patch
- Small patch possible, but with significant performance issues
- Old bug (since December 2005) and not reported for real-world code;
I think it is unlikely to be hit in real code as the example
is rather constructed*
* The bug only occurs if a subroutine accesses both a TRANSPOSEd variable,
which is passed as actual argument, and the same variable via host or use
association. In that case a temporary is needed for the actual argument.
Feel free to re-open if you think it really should be backported.
