A compiler bug in older versions of gcc makes it do unsafe optimizations at -O1
and higher. This manifested itself with (at least) gcc 4.5.2 on SmartOS because
it made V8 hang in a busy loop.

The only test using this is test/simple/test-fs-chmod.js, and it was
treating a.js and a1.js as two separate files, resulting in a race
condition. (Interestingly enough, it was *not* using the symlink file to
test lchmod, which uses a different temp file.)
