Bzzz. This is wrong on so many levels.

Please just use a sane optimization level when compiling if you don't know how the type system works (so you can send proper patches) and what you have to do to get the "faster" levels working. Thanks.

This has nothing to do with optimization level, it has to do with position independant executables.

Awaiting new patch.

You assume this user is using a hardened toolchain which includes -fpie in its cflags, this is still very much an issue even at -02.

CFLAGS="-O2 -march=native -pipe"

Those are my cflags on all my hardened systems. This is an issue with -fpie NOT optimization.

right.   still, this is quite an old bug.   time to retest with latest version or git.
