in thread if Digest::SHA1 loaded Can't load LibXML/LibXML.dll Invalid access to memory location

You should read ASLR (Address space layout randomization) and Windows ISV Software Security Defenses

Its kinda vague but I think it says windows-7 can have ASLR enabled if you flip some bits on all the dlls used

peflags --dynamicbase=true --nxcompat=true perl.exe libxml.dll ...

or LDFLAGS/LDDLFLAGS -Wl,--dynamicbase -Wl,--nxcompat

ASLR is supposed to replace that ImageBase stuff
