Re: [Patch, Fortran] PR54788 ICE on pointer-array element assignment


Am 28.06.2013 17:03, schrieb Dominique Dhumieres:
The following patchlet fixes the ICE for the test case bellow and AFAICT
gives the right error.  Regstrapped on x86_64-apple-darwin10.8.0.
OK for the trunk?

The patch is okay and sufficiently trivial. Committed as Rev. 200575.

Thanks for the patch!
