Bug ID: 83218 Summary: gforttran command fails to compile if fortran file is present inside folder "%+@" Product: gcc Version: 6.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: sanket.karnik.s at gmail dot com Target Milestone: --- I was trying to compile a Fortran file which was present inside a directory called "%+@". This works fine with gfortran 4.9, however, when I tried to do the same using gfortran 6.3 I get an error. I tried to compile a simple "Hello world" program but even that code failed to compile.

Reproduction steps from any directory: 1. % mkdir %+@ 2. %gedit %+@/hello_world.f90 3. copy following code and save the file: program hello print *, "Hello World!" end program hello 4. gfortran %+@/hello_world.f90 This should produce an error.
