Hi,
Some functions supplied by lua.cc crash on calling "luaL_error":
- enigma.GetAttrib with non existing attribute or pseudo-attribute "kind".
- enigma.GetKind(nil)
These crashes occur only on Windows but not on Linux. They are
independent of Lua 5.1 and 5.1.1.
The error handling does work in general on Windows, as incorrect calls like
enigma.SetItem(7,9, nil)
are reported correctly.
Please find attached a sample level with the different errors commented
out. Activate one after the other for testing.
Any ideas?
BTW calling enigma.GetAttrib with a non existing attribute will always
end in a level abortion as "luaL_error" will never return. Shouldn't we
skip this error message to return "nil" as prepared in lua.cc? At least
Andreas and I did expect nil for non existing attributes as we have no
other function to test the existance of an attribute.
