Похоже, проблема с указателем nullptr, указывает на строчки типа 

    mHashtable =  nullptr;

он хитро определен (файл  mfbt/NullPtr.h ):



#define mozilla_NullPtr_h_

#include "mozilla/Compiler.h"

#if defined(__clang__)
#  ifndef __has_extension
#    define __has_extension __has_feature
#  endif
#  if __has_extension(cxx_nullptr)
#    define MOZ_HAVE_CXX11_NULLPTR
#  endif
#elif defined(__GNUC__)
#  if defined(__GXX_EXPERIMENTAL_CXX0X__) || __cplusplus >= 
201103L
#    if MOZ_GCC_VERSION_AT_LEAST(4, 6, 0)
#      define MOZ_HAVE_CXX11_NULLPTR
#    endif
#  endif
#elif _MSC_VER >= 1600
# define MOZ_HAVE_CXX11_NULLPTR
#endif

/**
 * Use C++11 nullptr if available; otherwise use __null for gcc, 
or a 0 literal
 * with the correct size to match the size of a pointer on a 
given platform.
 */

#ifndef MOZ_HAVE_CXX11_NULLPTR
#  if defined(__GNUC__)
#    define nullptr __null
#  elif defined(_WIN64)
#    define nullptr 0LL
#  else
#    define nullptr 0L
#  endif
#endif

#endif  /* mozilla_NullPtr_h_ */
