* [Bug c++/104347] New: internal compiler error- default template arguments - missing angle brackets @ 2022-02-02 17:08 dev at gutoehrlein dot eu 2022-02-02 21:44 ` [Bug c++/104347] " pinskia at gcc dot gnu.org ` (4 more replies) 0 siblings, 5 replies; 6+ messages in thread From: dev at gutoehrlein dot eu @ 2022-02-02 17:08 UTC (permalink / raw) To: gcc-bugs https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104347 Bug ID: 104347 Summary: internal compiler error- default template arguments - missing angle brackets Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: dev at gutoehrlein dot eu Target Milestone: --- Created attachment 52330 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52330&action=edit code which crashes the compiler command to compile: g++ -o test -std=c++20 -O2 test.cpp ----- Version of g++: 11.2 OS: Ubuntu (Kernel: 5.13.0) ----- The code contains a missing "<>" in line 327. Line 328 (comment) contains the correct code. g++ crashes with an internal compiler error instead of displaying an error message. Additional info: * Can be also reproduced on https://godbolt.org/ * The current VS compiler also produces an internal compiler error. * Clang 13 parses the file and displays the appropriate error message: <source>:327:11: error: alias template 'SISpeed' requires template arguments; argument deduction only allowed for class templates ----- <source>: In function 'int main(int, char**)': <source>:327:19: internal compiler error: Segmentation fault 327 | SISpeed v = l / t; | ^ 0x1786229 internal_error(char const*, ...) ???:0 0x7d2840 template_parms_to_args(tree_node*) ???:0 0x7d68ed do_auto_deduction(tree_node*, tree_node*, tree_node*, int, auto_deduction_context, tree_node*, int) ???:0 0x7002b6 cp_finish_decl(tree_node*, tree_node*, bool, tree_node*, int) ???:0 0x7c47db c_parse_file() ???:0 0x896762 c_common_parse_file() ???:0 Please submit a full bug report, with preprocessed source if appropriate.
