#2794: Bootstrapping ghc-6.4.3 hangs in call to "ghc-pkg-inplace"

-----------------------+----------------------------------------------------
I want to bootstrap ghc-6.4.3 with ghc-6.2.2 on an i686 Linux system
based on libc-2.2.4. The bootstrap '''make''' runs ok until the
following command:
{{{
../utils/ghc-pkg/ghc-pkg-inplace --force --update-package
<package.conf.inplace
}}}
which "hangs forever" while chewing up cpu cycles.
Cd-ing into ''ghc-pkg'' and issuing
{{{
./ghc-pkg.bin --help
}}}
produces exactly the same effect. An '''strace''' on the latter
command results in an endless series of
{{{
sigreturn() = ? (mask now [])
--- SIGVTALRM (Virtual timer expired) ---
}}}
When running '''ghc-pkg.bin''' under the control of '''gdb''' and
interrupting with {{{C-c}}} always catches the execution inside of
{{{
__stginit_DistributionziCompatziReadP_ ()
}}}
which is a part of Cabal. However, the following trivial test program
does not get stuck in that call:
{{{
-- Compile with:
-- ghc -i../../lib/compat -L../../lib/compat -lghccompat \
-- -o use-readp use-readp.hs
import Distribution.Compat.ReadP
main :: IO ()
main = do
putStr "start.\n"
}}}
I'm not familiar enough with the ghc build system (nor Haskell) to know
what goes wrong here.
