--- Comment #8 from David Abdurachmanov <david.abdurachmanov at gmail dot com> 2013-01-04 11:31:21 UTC --- I have tested the trunk, rev 194883. Seems to compile the test case #1, but it still fails in the original program, Sherpa [1]. I am attaching pre-processed test case #2. Sadly, it includes <complex>. [1] https://sherpa.hepforge.org/trac/wiki ### ICE, SEGFAULT ### testcase.cpp: In constructor 'B<Tp>::B()': testcase.cpp:6:61: in constexpr expansion of 'std::complex<double>(1.0e+0)' testcase.cpp:6:61: internal compiler error: Segmentation fault std::complex<double>((true ? 1.0 : std::complex<double>())); ^ Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. ### COMPILE LINE ### g++ -m64 -O2 -std=c++11 -c testcase.cpp -fPIC -g -o ./testcase.o ### TEST CASE ### #include <complex> template <typename Tp> struct B { B() { std::complex<double>((true ? 1.0 : std::complex<double>())); } }; ### GCC FULL OUTPUT ### Using built-in specs.
