https://issues.dlang.org/show_bug.cgi?id=20685 Issue ID: 20685 Summary: Missing const in name mangling with C++ when using templates Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: andrej.mitrovich gmail.com cpp.cpp: ----- template<typename K, typename V> void cpp_test (const K&, const V&) { } #define INSTANTIATE(K, V) template void cpp_test<K, V>(const K&, const V&); INSTANTIATE(int, int) ----- d.d: ----- extern(C++) void cpp_test (K, V)(ref const K key, ref const V value); void main () { int i; cpp_test(i, i); } ----- $ g++ -c cpp.cpp -ocpp.o $ dmd -c d.d -ofd.o $ nm cpp.o | grep cpp_test 0000000000000000 W _Z8cpp_testIiiEvRKT_RKT0_ $ nm d.o | grep cpp_test U _Z8cpp_testIiiEvRT_RT0_ It seems that 'const' is missing. It seems similar to https://issues.dlang.org/show_bug.cgi?id=20336, only that here templates are involved. --
