TUT selftest fails with /safeseh #34

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Template Unit Test Framework selftest fails when built with /SAFESEH option.

This should not be caused by cxxrecord::catchguardhandler as it is in
SAFESEH table, however EH dispatcher don not call it.

Workaround: TUT works fine with /SAFESEH:NO option.

Note that selftest was passed at x64 mode.

selftest fails only in debug mode with /SAFESEH option.

selftest was failed with /safeseh and disabled /OPT:ICF.

Fixed in r700.

For now it is clear this fails only with /OPT:NOICF and is caused by thunks 
generated
by the linker for cxxrecord::catchguardhandler(). 

Workaround is to use /OPT:ICF for release builds and /SAFESEH:NO for debug ones.

r700 does *disassembling* to get the handler address from the thunk. This is 
overhead
and, I believe, workarround but not fix.
