The exception handling code in GCC has been getting a fair amount of
work done on it lately. However, it's not even attempting to be
thread-safe. Fixing that requires changing both the compiler and the
support code in libgcc. The compiler generates assignments to global
variables and calls or jumps into library code that reads them, with
no locking.

It should be. But it isn't with g++ right now.
