gcc5 @5.3.0_1: gfortran-mp-5 fails to compile a simple code

[clemreal]

Hello,

I am a beginner in fortran but I suspect a problem while compiling a very simple code.

1. The code I try to compile, written in hello.f90

program hello
  print *, "Hello World!"
end program hello

2. Compilation

I use the command:

gfortran-mp-5 -o hello hello.f90

3. Error printed in the terminal

<built-in>: internal compiler error: Illegal instruction: 4

<built-in>: internal compiler error: Abort trap: 6
gfortran-mp-5: internal compiler error: Abort trap: 6 (program f951)
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://trac.macports.org/newticket> for instructions.

4. Comments

The command to compile the code works on my personal computer with a version of gfortran 5.1.0. I need to compile this code on my professionnal computer (Mac OS 10.11.6) without the admin rigths.

The command gfortran-mp-5 --version returns:

I don't know anything about Fortran so I probably can't help you debug this further, but it might be useful to know if you see the same problem with gcc6 or gcc7.

The solution is to force uninstall and rebuild from source code the GMP and MPFR math libraries:

port uninstall -f gmp mpfr
port install -s gmp mpfr

After doing this, the gfortran-mp-5 runs just fine. Problem solved!

I know less about fortran than Ryan, but your test program builds and runs fine on MacOSX10.6 with gcc6, FWIW.

also, the current version of gcc5 is 5.40, and you're on 5.30, so you're a bit out of date there, FYI.

glad you fixed it.
