I heard that entering/exiting try-catch block with gcc cost 0 assembly
instructions (unlike msvc++), as gcc uses tables to derive the
corresponding catch handler from the instruction pointer. So,
-fno-exception inhibits generation of said tables while having little
if any effect on the amount of generated code.

Please correct me where I'm wrong.
