Bug ID: 98417
Summary: -internal compiler error when using -g
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: patrick.kox at commandoregel dot be
Target Milestone: ---
I'm new so I hope this is the correct way to report this.
When using the -g flag with the C++20 modules example from the wiki
(https://gcc.gnu.org/wiki/cxx-modules) the compiler gives an internal compiler
error.
This is with version (g++ (GCC) 11.0.0 20201220 (experimental)).
The output of the compiler is:
g++ -g -Wall -fmodules-ts -c -MMD -MP -o hello.o hello.cc
g++ -g -Wall -fmodules-ts -c -MMD -MP -o main.o main.cc
main.cc: In function ‘int main()’:
main.cc:11:3: internal compiler error: in gen_typedef_die, at dwarf2out.c:25373

make: *** [<builtin>: main.o] Error 1
removing the -g flag from the command solves the issue
