Bug ID: 70617 Summary: internal compiler error: Segmentation fault Product: gcc Version: 5.3.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: jan.sm...@alcatel-lucent.com Target Milestone: --- gcc (GCC) 5.3.1 20160404 Unfortunately I have been unable to get a reduced testcase to upload. Creduce keeps running in loops and minor modifications to the source make it go away. The code is proprietary and therefor I can not share it.
