Seems like probably Windows, where 0000007e would be Module Not Found.

The extension may have been dynamically linked to the CRT and require a version of the Microsoft C++ Redistributable installed. A guess based on project file is has for Jansson would be the 2010 version (32-bit). (The extension itself uses CMake, so project gets generated depending on what VS version's env you're in)
