I read here that
/SAFESEH is only valid when linking for x86 targets. /SAFESEH is not supported for platforms that already have the exception handlers noted. For example, on x64 and Itanium, all exception handlers are noted in the PDATA.
What does this mean? Is the SEH chain checked with a x64 target (stored into the PDATA structure) ? Or there is no safeSEH check with x64 targets?
