__cxa_guard_acquire.
SYNOPSIS
Inherits std::exception.
Public Member Functions
virtual const char * what () const 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.
