Bug ID: 107516 Summary: [13 Regression] ICE with -fwide-exec-charset=latin1 Product: gcc Version: 13.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: redi at gcc dot gnu.org Target Milestone: --- Compiling the attached code with -std=gnu++20 -fwide-exec-charset=latin1 gives an ICE with trunk. GCC 12 doesn't ICE, but maybe it's a --enable-checking=release thing (no ICE even with -fchecking=3 though). tmp$ ~/gcc/12.1/bin/g++ -std=c++20 suffix.cc -fwide-exec-charset=latin1 tmp$ ~/gcc/13/bin/g++ -std=c++20 suffix.cc -fwide-exec-charset=latin1 -freport-bug during RTL pass: expand suffix.cc: In function ‘auto __units_suffix() [with _Period = std::ratio<1, 1000>; _CharT = wchar_t]’: suffix.cc:97:22: internal compiler error: in get_constant_size, at varasm.cc:3418 97 | return L##suffix; \ | ^ suffix.cc:106:11: note: in expansion of macro ‘_GLIBCXX_UNITS_SUFFIX’ 106 | _GLIBCXX_UNITS_SUFFIX(milli, "ms") | ^~~~~~~~~~~~~~~~~~~~~ 0x8a6410 get_constant_size /home/jwakely/src/gcc/gcc/gcc/varasm.cc:3418 0x1519a88 assemble_constant_contents /home/jwakely/src/gcc/gcc/gcc/varasm.cc:3615 0x151af15 output_constant_def_contents /home/jwakely/src/gcc/gcc/gcc/varasm.cc:3666 0x151b264 maybe_output_constant_def_contents /home/jwakely/src/gcc/gcc/gcc/varasm.cc:3602 0x151b264 output_constant_def(tree_node*, int) /home/jwakely/src/gcc/gcc/gcc/varasm.cc:3568 0xe23b2e expand_expr_constant /home/jwakely/src/gcc/gcc/gcc/expr.cc:8592 0xe23b2e expand_expr_addr_expr_1 /home/jwakely/src/gcc/gcc/gcc/expr.cc:8619 0xe24169 expand_expr_addr_expr /home/jwakely/src/gcc/gcc/gcc/expr.cc:8812 0xe19464 expand_expr_real_1(tree_node*, rtx_def*, machine_mode, expand_modifier, rtx_def**, bool) /home/jwakely/src/gcc/gcc/gcc/expr.cc:12096 0xe26825 store_expr(tree_node*, rtx_def*, int, bool, bool) /home/jwakely/src/gcc/gcc/gcc/expr.cc:6330 0xe28090 expand_assignment(tree_node*, tree_node*, bool) /home/jwakely/src/gcc/gcc/gcc/expr.cc:6051 0xcf589c expand_gimple_stmt_1 /home/jwakely/src/gcc/gcc/gcc/cfgexpand.cc:3946 0xcf589c expand_gimple_stmt /home/jwakely/src/gcc/gcc/gcc/cfgexpand.cc:4044 0xcfc0ce expand_gimple_basic_block /home/jwakely/src/gcc/gcc/gcc/cfgexpand.cc:6096 0xcfdbe7 execute /home/jwakely/src/gcc/gcc/gcc/cfgexpand.cc:6822 Please submit a full bug report, with preprocessed source.
