Hi devs,
I've just hit on a strange bug, and I don't know where to start looking.
In my branch where I'm building support for dependent types
(github.com/goldfirere/ghc.git; branch: nokinds.... but you don't need to look
there) I'm going through the testsuite and picking off bugs one at a time. I'm
very puzzled by the output I'm getting from typecheck/should_compile/tc231,
which does a -ddump-tc. At the end, I see
...
Dependent modules: []
Dependent packages: [base-4.8.0.0, ghc-prim-0.3.1.0,
integer-gmp-1.0.0.0]
Notice the version number of integer-gmp. I haven't touched anything near
there! And, my integer-gmp.cabal file says 0.5.1.0, which is what I'd expect.
Sure enough, when I use the inplace `ghc-pkg list`, I see that I have
integer-gmp-1.0.0.0 installed, along with all the other boot packages with
their correct version numbers.
Any hints here? I can surely work around this, but it's very strange!
Thanks!
Richard
