Bug ID: 57556
Summary: [OOP][Regression] ICE with move_alloc on polymorphic
component
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: sfilippone at uniroma2 dot it
Created attachment 30274
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30274&action=edit
Test case
The attached code generates the ICE when compiled with -fcheck=all. Looks very
similar but independent of PR57542, since the patch for the latter was already
applied. Works with 4.7/4.8.
