Summary: ICE in finish_member_declaration() with --param
ggc-min-expand=0 --param ggc-min-heapsize=0
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
We ICE for the following C++ test case using a recent trunk (revision 170689)
and 4.5 branch (revision 170668) when we force GC to always run. Otherwise, we
do not ICE.
