Dear Cafe,

I'm not sure it is a bug or just designed behavior? But I can't install profiling-enabled exe with cabal 3.2.0.0, while direct running works correctly.

$ cabal --version
cabal-install version 3.2.0.0
compiled using version 3.2.0.0 of the Cabal library 
$ cabal run --enable-profiling --enable-executable-profiling  exe:els -- +RTS --info

Is there other options to get a profiling enabled exe installed?

Thanks with regards,
