Issue compiling with gfortran 4.9.0 on Mac OS 10.9.4

[nicofournier]

Compilation works fine with gfortran 4.8.2 but exits with the following error when using 4.9.0:

gfortran  -std=f2003 -fimplicit-none -frange-check -O2 -DFORCE_VECTORIZATION -fmax-errors=10 -pedantic -pedantic-errors -Waliasing -Wampersand -Wcharacter-truncation -Wline-truncation -Wsurprising -Wno-tabs -Wunderflow -ffpe-trap=invalid,zero,overflow -I../shared/  -c -o ../../obj/mesh/meshfem3D.o meshfem3D.f90

Sounds like you didn't run make clean after building with 4.8.2.

Also, are those patches really necessary? Please open a new issue for them if you are certain they are needed.

[nicofournier]

Well, except that I didn't have 4.5.8 installed when I built it first (clean OS install and fresh 4.9.0). So I am a bit confused. Will try it though. Good points re- the patches. SCOTCH is based on the User Manual recommendation. -restrict as a flag also did not work, hence the patches. Will do some more testing and open a new issue if needed

Probably a local install problem, since no problem is detected by BuildBot.
