Bug #: 51227
Summary: [c++0x] ICE with invalid parameter in lambda
expression
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: reichelt@gcc.gnu.org
The following invalid code snippet triggers an ICE when compiled with
"-std=c++0x" since the introduction of lambda expressions (GCC 4.5.0):
====================================
template<int> int foo()
{
[] (void i) { return 0; } (0);
}
void bar()
{
foo<0>();
}
====================================
bug.cc: In function 'int foo()':
bug.cc:3:12: error: 'i' has incomplete type
bug.cc:3:13: error: invalid use of 'void'
bug.cc: In instantiation of 'struct foo() [with int <anonymous> =
0]::<lambda>':
bug.cc:3:3: required from 'int foo() [with int <anonymous> = 0]'
bug.cc:8:10: required from here
bug.cc:3:4: internal compiler error: Segmentation fault
