Running this program when compiled with gfortran goes off into an infinite loop,
or tries to allocate a large amount of memory, resulting it the process being
killed.

[Bug fortran/22010] New: Namelists defined in modules not handled properly

[gcc-bugzilla at chatsubo dot lagged dot za dot net]

The following code (where input.dat is a file that does not
contain a debugging namelist entry) goes wrong:

MODULE debug
  LOGICAL debug_area
  NAMELIST/debugging/debug_area
END MODULE debug

PROGRAM ding
  USE debug
  IMPLICIT NONE
  INTEGER :: ios
  OPEN(unit=10, status='unknown', file='input.dat')
  READ(unit=10, nml=debugging,  iostat=ios)
  PRINT*, 'nml=debugging',ios
END PROGRAM ding

$ gfortran -o namelistding namelistding.f90 && ./namelistding
 nml=debugging  2

The following works properly:

PROGRAM ding
  IMPLICIT NONE
  LOGICAL debug_area
  NAMELIST/debugging/debug_area
  INTEGER :: ios
  OPEN(unit=10, status='unknown', file='input.dat')
  READ(unit=10, nml=debugging,  iostat=ios)
  PRINT*, 'nml=debugging',ios
END PROGRAM ding

$ gfortran -o namelistding namelistding.f90 && ./namelistding
 nml=debugging  -1

More interesting, the following also works:

MODULE debug
  LOGICAL debug_area
  NAMELIST/debugging/debug_area
END MODULE debug

PROGRAM ding
  USE debug
  IMPLICIT NONE
  NAMELIST/debugging/debug_area
  INTEGER :: ios
  OPEN(unit=10, status='unknown', file='input.dat')
  READ(unit=10, nml=debugging,  iostat=ios)
  PRINT*, 'nml=debugging',ios
END PROGRAM ding

$ gfortran -o namelistding namelistding.f90 && ./namelistding
 nml=debugging  -1
