Example code:
$ cat alloc.f90
INTEGER ERR,N
PARAMETER (N=10)
CHARACTER(LEN=40), POINTER :: vPTR(:)
CHARACTER(LEN=40), ALLOCATABLE :: vALLOC(:)
ALLOCATE(vPTR(N),STAT=ERR)
ALLOCATE(vALLOC(N),STAT=ERR)
vALLOC='A'
vPTR=vALLOC ! Line cause compiler error
WRITE(*,*) vPTR
DEALLOCATE(vPTR,STAT=ERR)
DEALLOCATE(vALLOC,STAT=ERR)
END
When compiling it an internal compiler errors arises:
$ /usr/local/bin/gfortran/irun/bin/gfortran -static -v --save-temps alloc.f90

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
ICE appears with CHARACTER type, REAL or INTEGER seems ok.
ICE appears only with POINTER to POINTER or mixed POINTER to/from
ALLOCATABLE arrays assigning, ALLOCATABLE to ALLOCATABLE have works.
