Bug #: 55824
Summary: [OOP] ICE with ALLOCATE and SOURCE= TRANSPOSE/RESHAPE
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org

Failing test case
The following example by Reinhold Bader gives an ICE.
It uses CLASS(*) but allegedly the issue also occurs with nonunlimited
polymorphics.
The ICE occurs for:
class(*), allocatable :: x(:,:), y(:,:), z(:)
...
allocate(y(3,3), source=transpose(x)) ! <<< ICE
...
allocate(z(9), source=reshape(x, (/ 9 /))) ! <<< ICE
