I know. That is why I put those comments there and why Eric commented
it out at the first place. At that time, ctors/dtors were in the
.text segment.

I think it is wrong to put the writable section into the .text section.
It will break any schemes which uses the .text section like

const char * const foo = "You should die if you modify it.";

There must be a bug in somewhere else if ld dies. It is not my
patch's fault.
