--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The
  MEM[(struct a *)&l].c = l$c_24;
in the function to be inlined is there since esra.  Arguably it is strange that
esra stores back into the parameter when it is const.
In C/C++ one can cast away the const, but if the parm isn't addressable and
there are no stores to it it shouldn't be modified.
