Bug #: 52487
Summary: [4.6/4.7 Regression] [C++11] ICE at
cp/semantics.c:5613 with lambda capturing reference to
incomplete type by value
Classification: Unclassified
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hevanen@googlemail.com
The following code snippet causes an ICE:
struct A;
void foo(A& a)
{
[=](){a;};
}
int main() {}
Confirmed with
gcc version 4.6.1 20110409 (prerelease) (Ubuntu 4.6.0-3~ppa1) and
GNU C++ (niXman build) version 4.7.0 20120203 (experimental) (i686-pc-mingw32)
The latter prints:
internal compiler error: in literal_type_p, at cp/semantics.c:5613
There is no ICE with this version:
GNU C++ (Ubuntu/Linaro 4.5.2-8ubuntu4) version 4.5.2 (x86_64-linux-gnu)
Instead, it prints the expected error message ("invalid use of incomplete type
‘struct A’").
