The -xc runtime option does just that, with a stack trace[0].

  ./app +RTS -xc
> Total lack of debugging tools

I wouldn't exactly say there is a total lack. To name a few:

Thread Scope: https://wiki.haskell.org/ThreadScope

Event Log: https://ghc.haskell.org/trac/ghc/wiki/EventLog (capable of live monitoring)

GHCi Debugger: https://downloads.haskell.org/~ghc/latest/docs/html/users_gu...

EKG: https://hackage.haskell.org/package/ekg

I also consider type system features to be a very useful form of tooling:

Typed Holes: https://downloads.haskell.org/~ghc/latest/docs/html/users_gu...

Deferring Type Errors: https://downloads.haskell.org/~ghc/latest/docs/html/users_gu...

Partial Type Signatures: https://downloads.haskell.org/~ghc/latest/docs/html/users_gu...

[0] - Can't direct link, look for -xc here: https://downloads.haskell.org/~ghc/latest/docs/html/users_gu...
