shared section "section" contains relocations; image may not run correctly
The linker emits this warning whenever you have a shared section to warn you of a potentially serious problem.
One way to share data between multiple processes is to mark a section as “shared.” Marking a section as shared can cause problems, however. For example, you have a DLL that contains declarations like this in a shared data section:
int var = 1;
int *pvar = &var;
The linker cannot resolve pvar because its value depends on where the DLL is loaded in memory, so it puts a relocation record in the DLL. When the DLL is loaded into memory, the address of var can be resolved and pvar assigned. If another process loads the same DLL but cannot load it at the same address, the relocation for the address of var will be wrong because the relocation was applied for the first process's address space.
