New description:

 Throwing a `std::runtime()` exception locks up.

 The lock up is in the exception clean up handler where the exception
 object is destructed. The destructor loops distructing the std::string
 object. The path ends up in libstdc++-v3/include/ext/atomicity.h line 48
 or __exchange_and_add.

 At a guess it would seem like the C++ atomics on i386 is broken or
 fragile.
