Bug ID: 107897
Summary: [13 Regression] ICE in verify_curr_properties, at
passes.cc:2201
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Started between 20221030 and 20221106,
with file g++.dg/cpp2a/concepts-lambda3.C :
$ gcc-13-20221127 -c concepts-lambda3.C -std=c++20 -flto -fno-inline
concepts-lambda3.C:40:13: error: mangling of 'main(int,
char**)::<lambda(auto:5)> [with auto:5 = int]' as
'_ZZ4mainENKUlT_E1_clIiEEDaS_' conflicts with a previous mangle
40 | auto a0 = [](IsNotLarge auto a) { return [](auto b){ return b; }; };
| ^
concepts-lambda3.C:37:3: note: previous mangling 'int main(int,
char**)::<lambda(auto:3)>::_ZZ4mainENKUlT_E1_clIiEEDaS_(int) const'
37 | [](auto t) requires true { return t; }(5);
| ^
concepts-lambda3.C:40:13: note: a later '-fabi-version=' (or =0) avoids this
error with a change in mangling
40 | auto a0 = [](IsNotLarge auto a) { return [](auto b){ return b; }; };
