Bug #: 55240
Summary: [c++0x] ICE on non-static data member initialization
using 'auto' variable from containing function
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bisq...@iki.fi
This code causes an ICE in GCC 4.7.1 and 4.7.2:
int main()
{
int q = 1;
struct test { int x = q; } instance;
}
tmpq.cc: In constructor 'constexpr main()::test::test()':
tmpq.cc:4:12: internal compiler error: in expand_expr_real_1, at expr.c:9122
It is notable that if the code is written like this, the error message changes.
int main()
{
int q = 1;
struct test { int x; test():x(q){} } instance;
}
tmpq.cc:5:35: error: use of 'auto' variable from containing function
tmpq.cc:3:9: error: 'int q' declared here
