NAME

       __gnu_cxx::recursive_init_error - Exception thrown by __cxa_guard_acquire.

       C++ 2011 6.7 [stmt.dcl]/4: If control re-enters the declaration recursively while the
       variable is being initialized, the behavior is undefined.

SYNOPSIS

       Inherits std::exception.

   Public Member Functions
       virtual const char * what () const _GLIBCXX_TXN_SAFE_DYN noexcept

Detailed Description

       Exception thrown by __cxa_guard_acquire.

       C++ 2011 6.7 [stmt.dcl]/4: If control re-enters the declaration recursively while the
       variable is being initialized, the behavior is undefined.

       Since we already have a library function to handle locking, we might as well check for
       this situation and throw an exception. We use the second byte of the guard variable to
       remember that we're in the middle of an initialization.
