Farid Zaripov commented on STDCXX-507:
--------------------------------------

This is the old known issue of the cygwin ld auto-import feature: http://www.cygwin.com/ml/cygwin/2004-09/msg01101.html

The possible solutions:
1) use __declspec (dllexport/dllimport) (disables auto-import feature)
2) use ld script (-Wl,--script,i386pe.x-no-rdata): http://qtwin.cvs.sourceforge.net/*checkout*/qtwin/qt-3/mkspecs/cygwin-g%2B%2B/i386pe.x-no-rdata?pathrev=QT_WIN32_3_3_BRANCH

Now I try to check the 1).

> Many utilities, examples and tests failed to start due to access violation while loading libstdxxx.dll. In night builds logs they all finished with status 5. The reason is access violation while loading libstdxxx.dll. All of them has many times duplicated imports (see the attached file) and I suppose that bug in ld utility.
