Bug #: 55652
Summary: [C++11][4.8] ICE (segfault) with templates and structs
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: david.abdurachma...@gmail.com

testcase used.
Hi folks,
I have started re-compiling my RPMs with GNU GCC 4.8.0 (revision 194323) to
check the status.
Below your will find the smallest test case I currently could produce showing
setfault (ICE). Yet I am still not fully sure what is causing it. I compiles w/
C++03, but not w/ C++11. It also compiles w/ GCC 4.7.2.
I am attaching *.ii.
## TESTCASE ##
#include <map>
template <typename T1, typename T2>
struct P {
T1 first;
T2 second;
P() : first(T1()), second(T2()) {}
};
struct E {
};
struct B {
B();
B(const B &obj) throw(E);
};
int main(void) {
P<B, std::map<B, B> > a;
return 0;
}
## COMPILE LINE ##
g++ -v -save-temps -std=c++11 -c -o test.o ./test.cxx
## GCC OUTPUT ##
./test.cxx: In function 'int main()':
./test.cxx:19:25: internal compiler error: Segmentation fault
P<B, std::map<B, B> > a;

## GCC FULL OUTPUT ##
Using built-in specs.
