Program that leads to gfortran SEGFAULTING
The problem is that when using gfortran to compile a simple program
(the source code for the program is attached) on the Raspberry Pi 2,
the compiler crashes, giving this error message:
bash-4.2$ gfortran-4.9 7.f95
f951: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See for instructions.
