Bug ID: 60366
Summary: ICE with self-invoking lambdas
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jengelh at inai dot de
This not-so-serious code:
$ cat w.cpp
int main(int argc, const char **argv)
{
auto f = [](const struct __lambda0 &self) { self(self); };
f(f);
return 0;
}
causes an ICE instead of just exiting(1):
$ g++ w.cpp -std=gnu++11 -o w -ggdb3 -Wall
w.cpp: In lambda function:
w.cpp:3:55: error: use of ‘main(int, const char**)::__lambda0’ before deduction
of ‘auto’
auto f = [](const struct __lambda0 &self) { self(self); };
^
w.cpp:3:55: error: invalid use of ‘auto’
g++: internal compiler error: Segmentation fault (program cc1plus)
