If I interrupt program running with "+RTS -p -hb" option, the program aborts with message below and I could only get empty heap profile.
Minimal case is below:
module Main where main :: IO () main = print $ sum [1..10000000000]
I compiled this code with "-prof -rtsopts" options, ran the program and then interrupt after several seconds.
$ ghc http-biographic-profile.hs -prof -rtsopts [1 of 1] Compiling Main ( http-biographic-profile.hs, http-biographic-profile.o ) Linking biographic-profile ... $ ./http-biographic-profile +RTS -hb -p ^Chttp-biographic-profile: internal error: Invalid object in processHeapClosureForDead(): 58 (GHC version 7.0.4 for x86_64_apple_darwin) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug zsh: abort ./http-biographic-profile +RTS -hb -p
Empty heap profile generated is below:
JOB "biographic-profile +RTS -hb -p" DATE "Thu May 17 17:12 2012" SAMPLE_UNIT "seconds" VALUE_UNIT "bytes" BEGIN_SAMPLE 0.00 END_SAMPLE 0.00
I reproduce this behaviour in environments below:
- GHC-7.0.4 (x86_64_apple_darwin, OS X 10.6.8, distributed with haskell-platform 2011.3.0.0)
- GHC-7.4.1 (x86_64_apple_darwin, OS X 10.6.8, installed from tarball, sandboxed with virthualenv)
I think "-hb" show work even when program interrupted, because "-hy", "-hd", "-hr" and so on works in such a situation. Is this a intended behaviour?
