// error-pattern:non-exhaustive match failure
fn test_box() { @100; }
fn test_str() {
    let res = alt false { true { "happy" } };
    assert res == "happy";
}
fn main() { test_box(); test_str(); }

About 80% of the time:

Assertion failed: (alloc->magic == MAGIC), function free, file ../src/rt/memory_region.cpp, line 41.

or

malloc: ... pointer being freed was not allocated

    This is bizarre that the call to test_box matters here.
