Bug ID: 61819
Summary: ICE in gfc_conv_descriptor_data_get
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: sfilippone at uniroma2 dot it
The attached code produces the ICE in both trunk and 4.9.0.
The code is from a test case I was trying to reduce while investigating a
memory leak, so something fishy is going on.
