Ix{Int}.index: Index (402849792) out of range ((0,100))

While building ghc HEAD pulled 2006-06-21 I got the following:

../../compiler/ghc-inplace -H16m -O -cpp -Iinclude -ignore-package HGL -O -Rghc-timing -fgenerics  -package base  -package X11 -fgenerics -split-objs -hisuf p_hi -hcsuf p_hc -osuf p_o -prof   -c Graphics/HGL/Draw/Font.hs -o Graphics/HGL/Draw/Font.p_o  -ohi Graphics/HGL/Draw/Font.p_hi

I used ghc 6.2.2 for bootstrapping

Is it possible that you had previously built GHC in this same tree, and you didn't 'make clean' after pulling? The Ix error is often a symptom of mismatched interface file formats.

[stepan@…]

Yes, it seems like I forgot to run 'make clean'.

In a new tree created with darcs everything builds fine. But when I run 'make maintainer-clean' in the existing tree I get the same error:

Do you mean that make maintainer-clean itself produces that error message, or the error message is produced when you try to make afterward? I just tried a make maintatiner-clean in libraries/HGL and it seemed to clean everything out just fine.
