See conan-io/conan-center-index#8895 (comment).
And the gory details in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66145.
Successful compilation, e.g. https://godbolt.org/x/qr1Yf7oo1, demonstrates that
std::ios_base::failure
is derived fromstd::system_error
in some environments with GCC 5, but since the error code is rarely useful, it's pragmatic just to delete this troublesome line of code.(Oh, and a comment fix I had lying around.)
