profiling a faulty program produces a segfault (4.06)

[Ian Jackson]

-davenant:~/junk> cat t.hs
main = error "bang!"
-davenant:~/junk> ghc t.hs
-davenant:~/junk> ./a.out 

Fail: bang!
-davenant:~/junk> ghc -prof -auto -auto-all t.hs
-davenant:~/junk> ./a.out 
Segmentation fault (core dumped)
-davenant:~/junk> ghc --version
The Glorious Glasgow Haskell Compilation System, version 4.06
-davenant:~/junk> 

This is with GHC 4.06, compiled by me for Linux/i386 using the
Debianisation support files which came with Debian's GHC
4.05.19991206-1 and (IIRC) the use of cvs update.
