Code example
By compiling and running the attached fortran code prof.f90
You get this error
$ gfortran -Wl,-z,noexecstack prog.f90 ; ./a.out
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7f5d7e300e3a
#1 0x7f5d7e30002d
#2 0x7f5d7d7f676f
#3 0x7ffd879cf620
Segmentation fault (core dumped)
without any flag you get
gfortran prog.f90
$ ./a.out

Unfortunately this flag is present in MPICH alias mpif90.
I get the bug on fedora 24 with gcc version 6.1.1 20160621
