// This test makes sure that full backtraces are used for ICEs when
// RUST_BACKTRACE is not set. It does this by checking for the presence of
// `__rust_{begin,end}_short_backtrace` markers, which only appear in full
// backtraces. The rest of the backtrace is filtered out.
//
// Ignored on msvc becaue the `__rust_{begin,end}_short_backtrace` symbols
// aren't reliable.
