--- Begin Message ---Package: g++-10 Version: 10.2.0-16 Severity: normal Tags: upstream Dear Maintainer, * What led up to the situation? Compiling the following code crashes g++-10: // g++-10 -std=c++2a -o /tmp/example.cpp.o -c example.cpp enum class MyEnumClass { A }; struct MyClass { MyEnumClass foobar : 8 { MyEnumClass::A }; }; bool some_function(MyClass x) { switch (x.foobar) { case MyEnumClass::A: return false; } } See at the bottom the exact invocation, error messages, and g++ version. This bug is a regression: g++-9 does *not* crash when compiling the above code. * What exactly did you do (or not do) that was effective (or ineffective)? The enum-class, bit-packing, seemingly incomplete switch-case, non-constant switch-argument, all seem to be necessary to trigger the bug. * What was the outcome of this action? Compiler crash (error message see below) * What outcome did you expect instead? Either a successful compilation, or a compilation error; but not a compiler crash. Full error message and versions: $ /usr/bin/g++-10 -std=c++2a -o /tmp/example.cpp.o -c example.cpp example.cpp: In function ‘bool some_function(MyClass)’: example.cpp:6:6: error: type precision mismatch in switch statement 6 | bool some_function(MyClass x) | ^~~~~~~~~~~~~ switch (_1) <default: <D.2095>, case 0: <D.2092>> example.cpp:6:6: internal compiler error: ‘verify_gimple’ failed 0x128422d verify_gimple_in_seq(gimple*) ../../src/gcc/tree-cfg.c:5144 0xf85436 gimplify_body(tree_node*, bool) ../../src/gcc/gimplify.c:14888 0xf856a3 gimplify_function_tree(tree_node*) ../../src/gcc/gimplify.c:14978 0xdbbe27 cgraph_node::analyze() ../../src/gcc/cgraphunit.c:670 0xdbee27 analyze_functions ../../src/gcc/cgraphunit.c:1227 0xdbf9f2 symbol_table::finalize_compilation_unit() ../../src/gcc/cgraphunit.c:2986 Please submit a full bug report, with preprocessed source if appropriate.
