Summary: tmp file not found after ghci :reload

Initial Comment:
In ghci, I often see this:

Main> :reload
Compiling HsParser         ( flhsparser/HsParser.hs,
interpreted )
*** Exception: does not exist
Action: openFile
Reason: No such file or directory
File: /tmp/ghc42863.hspp

This was present in 5.02.1 and still is in 5.02.2.

No, there's definitely nothing being removed behind GHCi's back.
(I could tell a long story about how I know.  For lack of
space, I'll
say that I know.  Definitely.)

No bug found (we believe that the /tmp file is being removed 
behind GHCi's back).  GHCi should recover more gracefully 
but it's low down the priority list.

Do you by any chance have a cron job that periodically 
cleans old files from /tmp?  It sounds like these files 
are getting removed behind GHCi's back.

Nevertheless, I suppose GHCi should recover gracefully 
since it's only the preprocessed file being cached 
in /tmp.  I'll look into it.

Unfortunately, it happens spuriously.  But if I keep
a session open long enough (between 10 minutes and 2 hours)
it happens inevitably.

For the record, this is on FreeBSD 4.3.

I can't repeat this bug.  Can you give any more 
information?  Is there a repeatable example or does it 
just happen randomly?
