Hi, Thomas, I tried gcc-9-branch and I could build MPICH f08 with it. I could also reproduce the problem Pedro Ricardo Souza reported. Could you check if it is a gcc bug in handling type(*), dimension(..) --Junchao Zhang On Thu, Nov 14, 2019 at 6:27 AM Thomas König via discuss <[email protected]<mailto:[email protected]>> wrote: Hi, just a general remark on this. If you were using gfortran 9, that has seen a fair number of bug fixes in that field in the recent weeks, which will be included in the next release of gcc 9 and the upcoming release of gcc 10. If you can, you might give the current gcc 9 branch a spin to see if the problem goes away. Any additional bug reports would be wecome 😉 _______________________________________________ discuss mailing list [email protected]<mailto:[email protected]> To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
