Summary: ICE: segmentation fault with -Wall
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: g...@abeckmann.de
I get an "internal compiler error: Segmentation fault" when compiling this code
with 4.5.2/4.6.0 and -Wall. The problem disappears if I remove -Wall.
4.4.5 and 4.3.x report "error: statement cannot resolve address of overloaded
function"
