negative `bytes' in :set +s

2004-05-24 Thread Serge D. Mechveliani 
Dear GHC team,

My DoCon test under  ghc-6-2-branch  performs like this

  ghc $pcpdocon --make T_
  ...
  ghci $pcpdocon T_ ...
  ... 
  Prelude T_> :set +s
  Prelude T_> test "log"
  ...
  *** Test FINISHED ***
  ...
  (35.02 secs, -990807880 bytes)

`:set +s'  is very usable, and the spent number of bytes is 
informative.
And it shows as negative.
Maybe, this can fixed by replacing of  Int  with  Integer ?
Just one more avidence of Int being a bug?

Recall also of the Set cardinality and such.

With kind regards,

-

Summary: Problem with where clause and Template Haskell

Initial Comment:
When compiling the two files attached, the following
happens:


$ ./compile.sh 
Chasing modules from: TemplateTryOut.hs
Skipping  Templates( ./Templates.hs,
./Templates.o )
Compiling Main ( TemplateTryOut.hs,
TemplateTryOut.o )
Loading package base ... linking ... done.
Loading package haskell98 ... linking ... done.
Loading package haskell-src ... linking ... done.
compiling template
ghc-6.2.1: panic! (the `impossible' happened, GHC
version 6.2.1):
nameModule readTread_d1z7

Please report it as a compiler bug to

or http://sourceforge.net/projects/ghc/.


I think it's a problem with template haskell. The first
call of 'template' in TemplateTryOut.hs (line 10)
succeeds, as you can see from the message 'compiling
template'. The second call in line 17 fails. The only
difference between these 2 calls is the where clause.
