External TH interpreter crashes with ghc: ghc-iserv terminated (-6)
Summary
The options to profile Template Haskell seem to crash with ghc: ghc-iserv terminated (-6)
Steps to reproduce
The following program crashes for me:
{-# LANGUAGE TemplateHaskell #-}
{-# OPTIONS_GHC -pgmi /home/sandy/.stack/programs/x86_64-linux/ghc-tinfo6-8.8.2/lib/ghc-8.8.2/bin/ghc-iserv-prof -fexternal-interpreter -opti+RTS -opti-p #-}
module ListPresentation where
blah = $([e| undefined |])
Note that I'm running this via stack, thus the janky -pgmi
option. I'm compiling with the following flags: --enable-library-profiling --enable-profiling --ghc-options -fprof-auto --ghc-options -fprof-cafs
.
Result:
ghc-iserv-prof: internal error: PAP object entered!
(GHC version 8.8.2 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
/home/sandy/prj/algebra-checkers/src/ListPresentation.hs:8:8: error:
• Exception when trying to run compile-time code:
ghc: ghc-iserv terminated (-6)
Code: [| undefined |]
• In the untyped splice: $([| undefined |])
|
8 | blah = $([e| undefined |])
| ^^^^^^^^^^^^^^^^^^^
Expected behavior
I expect the splice to work properly, and for me to get a profile dump.
Environment
- GHC version used: 8.8.2, and I'm also seeing it on 8.6.5
