[LD BUG] Delay import library combined with __declspec(dllimport) produces bogus output files

    XMLWordPrintable

Details

    Description

      Using a delay import library with functions which are declared in their header files as __declspec(dllimport) (e.g. ws2_32 functions) fails.
      This will cause a run-time failure when any such function is called, by jumping to the address '6'.

      This is a bug in binutils.

      A detailed test case can be found at:
      https://home.tfaber.net/~thfabba/pub/delaylib/

      Workarounds include:

      • linking the individual object files from the delay import lib
      • not using __declspec(dllimport) on such functions
      • (untested) referencing the function(s) in question at least once without using the dllimport attribute

      This has been tested with RosBE's binutils (2.20.51.20091222). Tests with later versions to come...
