Starting application from a directory with some kernel32.dll

[Uwe Bonnes]

Hallo,

when an application is run in a directory, where there is also a kernel32.dll,
and this is _not_ the system directory, MODULE_GetLoadOrder doesn't strip
the path and therefore crashes when native kernel32.dll is loaded.

While the header of MODULE_GetLoadOrder talks about "any path is stripped",
the function only strips the path for "16 bit modules or if the module
resides in the system directory "

Is this intended behaviour?

Bye

Wouldn't using a native kernel32.dll be a bad and a
snowballs-chance-in-hell-of-working thing anyway? :)

Yes, there can be multiple versions of a 32-bit dll with the same name
in different directories, and we have to be able to configure them
separately.

But loading native kernel32 and friends will lead to a crash. Would you
abject an explicit check for those?

As long as it is configurable that would be acceptable. But you cannot
simply hard-code kernel32 as builtin all the time, there may be cases
where you want to load the native. And note that you can already
specify a full path in the load order config so you could use that to
solve the problem in your case.
