Bug ID: 88537 Summary: class nontype template parameter debug mode crash in dwarf2out.c Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: hanicka at hanicka dot net Target Milestone: --- Created attachment 45253 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45253&action=edit minimal example which will crash with enabled debug symbols I found that gcc is crashing in gcc9crash.cpp:13:1: internal compiler error: in tree_add_const_value_attribute, at dwarf2out.c:20243 when I tried to emit debug symbols in a program with a "class nontype template parameter" Crashing code is attached. You can see it also here: https://gcc.godbolt.org/z/NOkj54 Compilation with: g++-HEAD gcc9crash.cpp -std=c++2a -ggdb -v Using built-in specs.
