Access violation in generated code with runghc and Yesod devel server

Summary

When using yesod devel, runghc will crash with "Access violation in generated code when executing data at (memory address)." After yesod devel tries again a few times, it works. Another access violation always happens again when quitting yesod devel with Ctrl+C, though.

Steps to reproduce

  1. Follow the Yesod quick start with the yesodweb/simple scaffold. (The scaffold is pretty large, so I have a smaller reproduction case based on https://github.com/yesodweb/yesod/tree/master/yesod-bin/devel-example, please let me know if that'd be helpful to include.)
  2. Run stack exec -- yesod devel.

Several access violation messages are printed:

Access violation in generated code when executing data at 0x12d93f10

 Attempting to reconstruct a stack trace...

   Frame        Code address

Access violation in generated code when executing data at 0x0

 Attempting to reconstruct a stack trace...


NOTE: Symbols could not be loaded. Addresses may be unresolved.

   Frame        Code address
Null address

Eventually, it will work and Yesod will say that the application has been launched. I have another Yesod project with the same problem but a more detailed message (I'm not sure what the difference is):


Access violation in generated code when reading 0xffffffffffffffff

 Attempting to reconstruct a stack trace...


NOTE: Symbols could not be loaded. Addresses may be unresolved.

   ... (maximum recursion depth reached.)

Expected behavior

There should be no access violation errors.

This problem doesn't occur with GHC 8.6.5, but it does occur with GHC 8.10.3 and 8.8.4. Also, the problem doesn't happen when building or running the project with stack build or stack run. It only happens with stack exec -- yesod devel, which uses stack runghc.

Environment

  • GHC version used: 8.10.3, 8.8.4

Optional:

  • Operating System: Windows 10
  • System Architecture: x86-64
