Test panic on riscv64

Not really sure how to debug this, when trying to merge #58 , tests on riscv64 panic with:

failures:

It appears that this might have something to do with cancellation, since all of these test cases exercise failure scenarios

[alexcrichton]

I can't reproduce the failures on x64, even with the same compile flags. I can reproduce with riscv64 emulation but only with CI's compile flags.

My guess is that this is Rust/LLVM-level UB somewhere.

This might be fixed by the use-after-free bug Alex found and fixed in #107, so we should rebase onto main and retest. If it's still broken, I'll dig into it on Monday.
