Bug ID: 114525 Summary: Incorrect code generated when setting a value through a pointer-to-member on a ternary returning an object reference Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: dragonroot at gmail dot com Target Milestone: --- The following program incorrectly outputs 1 on every GCC I've tried (via godbolt.org), while every clang version there correctly outputs 2. ============== #include <stdio.h> struct Foo { int x; }; Foo & get( Foo & v ) { return v; } int main() { Foo v; v.x = 1; bool cond = true; ( cond ? get( v ) : get( v ) ).*( &Foo::x ) = 2; // Should output 2, but outputs 1 printf( "%d\n", v.x ); } ==============
