Disabling them breaks build on archs using GCC. The problem is at line 156 of bits/basic_ios.h: if (this->exceptions() & __state) __throw_exception_again; With exceptions disabled __throw_exception_again is defined as #define __throw_exception_again at line 45 of exception_defines.h and the code results in an empty loop body, which fails because of -Werror.
