under Windows Server 2003 when DEP is enabled, but haven’t seen it on
other platforms. If I recall, there is code in version.dll which calls
LoadResource with RT_VERSION and then expects to be able to write to pages that
are clearly marked not-writable in the PE image. The pages remain
read-only until after a call to GetVersionInfo so something in the kernel is
altering them. I didn’t dig into it, but thought it was really
weird. When I turn off DEP for that program I got different behavior.
I don’t know what this means for wine but maybe that is useful… Jonathan |
