quickfix file fails to generate if stack exists unexpectedly

[xave]

Running a command such as ghcid -o quickfix --command="stack build --test --pedantic --fast --ghc-options='-DDEVELOPMENT -fobject-code -j +RTS -A64m -n2m -RTS'" fails to generate a quickfix file if stack exists with:

Command "stack build --test --pedantic --fast --ghc-options='-DDEVELOPMENT -fobject-code -j +RTS -A64m -n2m -RTS'" 

exited unexpectedly with error message:     Process exited with code: ExitFailure 1

*Current behavior*
On failure, no quickfix file is generated at all. 

*Expected behavior*
The quickfix file would be generated even if the process is interrupted.

Are you expecting a blank quickfix file in that case?
