Dear Developers,

 

I am writing you because openf90 failed to compile a very simple Fortran's subroutine. The corresponding error is given below:

 

openf90 -c -g -O0  -ftpp  lexical.bug.f

Signal: Segmentation fault in Front End Parse/Semantic phase.

Error: Signal Segmentation fault in phase Front End Parse/Semantic -- processing aborted

Enclosed please find the source file and needed system information.

 

It looks like a compiler bug because this example can be successfully processed and compiled  using many others compilers such as g77/gfortran, ifort, Sun's/Oracle's f90.
