--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, we really wrongly propagate 0 to x:
$ cat xxx.ltrans0.075i.cp
;; Function foo.constprop (foo.constprop.1, funcdef_no=3, decl_uid=4078,
cgraph_uid=1, symbol_order=5) (executed once)
Modification phase of node foo.constprop/5
Adjusting mask for param 0 to 0x0
Setting nonnull for 0
foo.constprop (double * a)
{
double x;
<bb 3> [100.00%] [count: INV]:
<bb 2> [100.00%] [count: INV]:
*a_2(D) = x_1(D);
return;
}
Started with r241990.
