Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2016-02-11 Ever confirmed|0 |1 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- We ICE expanding _4(D) in _5 = _4(D) /[ex] 4; But (gdb) p context $7 = <function_decl 0x7ffff69e6d20 main> (gdb) p current_function_decl $8 = <function_decl 0x7ffff69e6e00 operator()> for its underlying decl. So we somehow failed to properly remap things here (and appearantly have no verification for this).
