tree dump of failing test

integer, target :: tgt = 45
  type :: t
    integer, pointer :: i => tgt
  end type
  type(t), allocatable :: c(:)[:]

  allocate(c(10)[*])
  deallocate(c)
end

fails with:

[pault@pc30 pr83076]$ ~/irun/bin/gfortran -static-libgfortran test.f90  -fdump-tree-original -O3 -fcoarray=lib -lcaf_single -g
[pault@pc30 pr83076]$ ./a.out
At line 8 of file test.f90
Fortran runtime error: Attempt to DEALLOCATE unallocated 'c'

Error termination. Backtrace:

The tree dump is attached.

The version with an allocatable component works as expected.
