Apparently. I rebased the DLL alone and afterwards file simply stopped working. The DLL has a base address of 0x6a500000. Even rebasing to the very same address results in a coredump! The DLL has been built with -static-libgcc. Assuming that this might have been the reason I rebuilt the file package without -static-libgcc, so the DLL now depends on cyggcc_s.dll. And, guess what, afterwards the DLL is rebaseable just fine. Dave? Any idea why this occurs? The crash happens when the Cygwin DLL is running the ctors list. Given that the file package is using plain C, it seems that a static libgcc is non-relocatable for whatever reason. For the time being, I create and uploaded a new file package which depends on gcc4-runtime.
