Correctly? 

If this is correct, why isn't it the default? What exactly does it do to 
the executable?

It doesn't seem to be a documented gcc option, either.

Sorry for being so pushy, but I'm the author of a malloc debugger that's
already had to jump through quite a few hoops due to oddities in glibc and
gcc, and I just want to know exactly what's going on before I tell my users
that to get the full feature set, they have to build their executables
"correctly."
