[Bug testsuite/32038] New: gfortran.dg/pr25603.f is invalid code

[fxcoudert at gcc dot gnu dot org]

The testcase gfortran.dg/pr25603.f is invalid code. The following variables are
not initialized:

  lhelpa lhelp lcn lbn lan ldcdy ldcdx lkm ltm lvg lug lvm lum lhvar lzet ldep
  lvdep ltstr lustr lobuk ltavr lsteph lhmix lz0 lelevy lelevx lelev ldkzh
ldkzm
  lq lpstep lpi lwz lvstep lvy lustep lux ltstep lpot lcstep lc

They should be initialized with a value (like 1) if the test is to be run,
otherwise we access array elements out of range. I suggest the following patch
be applied:

The initial reason I catched this is that I sometimes run the testsuite with
-fbounds-check, which fails in this case.
