Steps to reproduce

  1. Clone and checkout latest master of Swift Crypto
  2. Edit the manifest to enable the CRYPTO_IN_SWIFTPM_FORCE_BUILD_API flag
  3. Run swift test from the command line

Tests are fine when run from Xcode

Even though the exit code is different, this is probably related to SR-12424. Can confirm the tests work fine from the command line in 5.3.

Hmm, taking a look at the crash report and the binary I don't immediately think this is the same as SR-12424. It manifests in the same situation, and may have similar causes, but the manifested behaviour is different. In particular, seeing a SIGILL from this code (entirely assertion free, with no ud2 to be found) is a bit alarming. I think I'll need to try to get a reproducer.

Ok, this is bizarre: I can reproduce a problem, not exactly this one. I am getting a SIGSEGV somewhere entirely else in the code, but in the same test. ASAN is clean (and indeed prevents the crash from happening at all, which suggests a stack smasher).

Note that I can't reproduce this when using Swift 5.3, just as @0xTim cannot, so that's a decent workaround for now while I dig in.

As a side note for future self: an update to BoringSSL does not fix this issue, so that's not going to be a suitable workaround. I didn't really think it would, but worth noting explicitly.
