[Bug fortran/29744] New: [Regression] Type renaming crashes gfortran with excessive memory usage

[anlauf at gmx dot de]

Hi,

the code sample from PR 19362 crashes for me after eating all
main memory.  I checked that a copy of gfortran from 20060710
still works, while the copy from 20060904 and all later versions
crash.

The problems appears to be related to the renaming of the derived
type from the included module.  Maybe it's some infinite recursion?

(For testers: I suggest to set a suitable ulimit, e.g.
"ulimit -v 50000" before calling gfortran on this example
to avoid thrashing).
