That sounds fine, although I suppose a determined user could choose
options that trigger the bug. It looks to me as though the -O options may
be shorthand for combinations of -f options. The gcc info pages say:
When you specify `-O', the compiler turns on `-fthread-jumps' and
`-fdefer-pop' on all machines. The compiler turns on
`-fdelayed-branch' on machines that have delay slots, and
`-fomit-frame-pointer' on machines that can support debugging even
without a frame pointer. On some machines the compiler also turns
on other flags.
Anyway, go ahead with your idea.
