GHCs json profiling output is not escaped correctly.
Summary
Quoting from stack overflow
JSON is pretty liberal: The only characters you must escape are \, ", and control codes (anything less than U+0020).But GHC produces strings like:
"arguments": ["E:\ghc_inferTags\_prof\stage1\bin\ghc.exe", "-O", "-fforce-recomp", "Distribution/Compat/Lens.hs"],Steps to reproduce
Use +RTS -pj on a profiling enabled program.
Expected behavior
The json should be properly escaped.
