Good morning.
I’m investigating new features of VS 2015 for future migrating of our
application, and find out that the previous working code of lo4cxx is now
broken.
We have a common application level configuration file, where there is a section
dedicated to log configuration. We read that section as a text and populate it
via code like (sniplet…)
log4cxx::helpers::Properties basicProps;
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> cvt;
const std::wstring wName = cvt.from_bytes(name); //name, read from file
const std::wstring wValue = cvt.from_bytes(value); //value, read from file
basicProps.setProperty(wName, wValue);
After setProperty call I get an heap corruption, imo, assertion (assert.png)
The stack looks like (stack.txt).
setProperty returns LogString, so if I write
log4cxx::LogString& v = basicProps.setProperty(wName, wValue);
the program successfully runs on this line, but still crashes, with the same
exception at the end of the scope.
To be able to compile, I made some changes to log4cxx.h , like from the link
https://issues.apache.org/jira/secure/attachment/12596517/msvs2012.patch
Compilers used:
OS: windows server 2008
Compilation: 64 bit
All compilers are run with support of C++11.
Visual Studio 2014 (v140) - Crash
Visual Studio 2013 (v120) - Crash
Visual Studio 2012 (v110) - Ok, but that was expected, it is what we use now
Intel Compiler 16 - Crash
Intel Compiler 14 - Ok, again, it is what we are using now
What can I do to overcome this issue. ?
P.S:
What I tried so far.
1) Implement my std::map with std::wstring and feed it into the
PropertyConfigurator. Same story, cause inside it uses same setProperty method.
2) Save log4cxx configuration section into the separate file and read it
via overload of configure
log4cxx::PropertyConfigurator::configure(log4cxx::File("C:\\log4.txt"));
Logger still not able to initialize, giving errors.
Repeat, it’s enough to change a compiler (from one listed above) and all works
perfectly.
Thank you.
