---------------------------------------
Summary: StdMutexMgr not working properly on VS2013 / Windows 7
Key: XERCESC-2165
URL: https://issues.apache.org/jira/browse/XERCESC-2165
Project: Xerces-C++
Issue Type: Bug
Components: Utilities
Affects Versions: 3.2.2
Reporter: Andreas Kleber
Attachments: xerces-hang.png
I am building a dynamic library which statically links OpenDSS, which
statically links ACE which statically links xerces-c with Visual Studio 2013.
When I run my application on Windows 7 the loading of my dll hands during
static initialization in StdMutexManager::lock(). See attached screenshot.
On windows 10 the same binaries work as expected.
I am building xerces 3.2.2 with default parameters as static library with
VS2013. During my investigation I found that xerces 3.2.1 works as well as
specifying the WindowsMutexMgr during configure, because, well, StdMutexMgr was
introduced in 3.2.2. Btw, this introduction of a new default Mutex Manager (at
least default in my environment) is not mentioned in the release notes. Whould
have helped me a lot....
In my environment all test pass on Windows 7 with StdMutexMgr.
Additional note:
[Microsoft|[https://docs.microsoft.com/en-us/windows/desktop/dlls/dynamic-link-library-best-practices]]
recommends not to acquire syncronization during dllmain.
As Windows 7 and VS 2013 are old and a workaround exists, this issue here is
intended as "known issue".
