Fails here as well on g++-7.3.0. g++-8.1.0 seems to survive just fine. Filed bug upstream as https://gcc.gnu.org/PR86353 Upstream is not comfortabe backporting the fix to gcc-7. I'm afraid you'll need to work it around on package level. |
g++-7.3.0 -std=c++17 gives an internal compiler error g++-7.3.0 -std=c++14 works g++-6.4.0 -std=c++17 works g++-6.4.0 -std=c++14 works Reproducible: Always Steps to Reproduce: 1. $ g++-7.3.0 -std=c++17 -c -o ouch.o ice.cpp 2. $ g++-7.3.0 -std=c++17 -c -o ouch.o ice2.cpp 3. $ g++-7.3.0 -std=c++17 -c -o ouch.o ice3.cpp Actual Results: ice3.cpp: In function ‘void __static_initialization_and_destruction_0(int, int)’: ice3.cpp:9:16: internal compiler error: in gimplify_expr, at gimplify.c:12200 d<3, float> j(1); ^ Please submit a full bug report, with preprocessed source if appropriate. See <https://bugs.gentoo.org/> for instructions. Expected Results: No internal compiler errors. Reduced with creduce. ice.cpp only gives an internal compiler error with the "# 7 "/usr/include/glm/gtc/quaternion.hpp" 3" line, and correctly gives sensible error messages without it. It's probably invalid C++, but compiles fine with g++-6.4.0 and/or -std=c++14. ice2.cpp is probably valid C++. ice3.cpp is a manually-reduced version of ice2.cpp.
