I analyze FreePascal exceptions handling. To study it, I wrote units
with functions fpc_NNN and not use try-except-finally. It catches
raised software exceptions. But I want also to catch hardware
exceptions. In procedure Exe_entry is install_exception_handlers. It
install syswin32_i386_exception_handler by
SetUnhandledExceptionFilter.
But is problem: function (in system.pp)
syswin32_i386_exception_handler compares: "if
excep^.ContextRecord^.SegSs = _SS then".  _SS is stack segment of
program, but in ContextRecord^.SegSs is strange value.

you better subscribe to the fpc mailing-list, and ask there. You are
more likely to get a response there.
