Linking to static 64bit libboost_thread fails DLL initialization

Reported by: Teemu Ikonen <teemu.ikonen@…> Owned by: viboes
Milestone: Boost 1.65.0 Component: thread
Version: Boost 1.63.0 Severity: Showstopper
Keywords: Cc:


If DLL links to static boost thread library the dll can not initialize and any exe that uses the DLL fails with error code (0xc0000142) 'DLL Initialization Failed'.

I've attached an minimal example project to demonstrate the problem. The package includes static boost libraries that were built with steps given below.

This example produces a thedll.dll that links libboost_thread (does not use any headers) and then theexe.exe that links to thedll.dll. theexe.exe fails to start with attached error prompt.

Root cause of the fail is beyond me, but I traced debugger to dll_dllmain.cpp on line 57. Here _initterm_e returns non-zero value and thedll.dll init fails. This happens only if libboost_thread is linked to the dll.

Maximum attachment size was mere few hundred kb's so I'm linking stuff here. Also I can't use proper urls as Trac will reject my comment as spam.. sigh.



Some debug screencaptures

Traced the error to a call to PVAPI on_tls_prepare(). This function gets called by _initterm_e that expects it to return 0 on success.

However in boost PVAPI is defined as void return type. I think this test is wrong for _MSC_VER 1910 in tss_pe.cpp.

  #if (_MSC_VER < 1300) || (_MSC_VER > 1900) // 1300 == VC++ 7.0, 1900 == VC++ 14.0
        typedef void (__cdecl *_PVFV)();
        #define INIRETSUCCESS
        #define PVAPI void __cdecl
        typedef int (__cdecl *_PVFV)();
        #define INIRETSUCCESS 0
        #define PVAPI int __cdecl

The runtime initializer function is supposed to return an int
