[fpc-devel] Object checks

If I may, a couple of queries about code generated for object checking
when range checks are on (-Cr):
An explicit check for nil is generated, which seems redundant, as any
attempt to use the value will generate a SIGSEGV anyway on most
platforms, or am I missing something?
If the fpc_check_object fails it calls RunError, which forces the
application to terminate, whereas a SIGSEGV will raise an exception and
give the user the option of continuing (at least in an LCL app). Is
there any reason why fpc_check_object does not call HandleError?
