---------------------------------+------------------------------------------
Since at least 5f37e0c ghc has failed to build for me. The failure occurs
early in the final stage build, showing up as,
{{{
"inplace/bin/ghc-stage2" -fPIC -dynamic -H32m -O -hide-all-packages -i

/m/vinci7/data1/dietz/ghc/ghc/inplace/lib/settings: openFile: does not
exist (No such file or directory)
}}}
Investigation with strace shows that the path passed to open() has been
corrupted,
{{{
open("/m/vinci7/data1/dietz/ghc/ghc/inplace/lib/settin@\270\215\240\347\277\212",
O_RDONLY|O_NOCTTY|O_NONBLOCK) = -1 ENOENT (No such file or directory)
}}}
Furthermore, the stage 1 testsuite fails immediately,
{{{
$ make
../mk/boilerplate.mk:149: ../mk
/ghcconfig_m_vinci7_data1_dietz_ghc_ghc_inplace_bin_ghc-stage2.mk: No such
file or directory
../mk/ghc-config "/m/vinci7/data1/dietz/ghc/ghc/inplace/bin/ghc-stage2"
>"../mk/ghcconfig_m_vinci7_data1_dietz_ghc_ghc_inplace_bin_ghc-stage2.mk";
if [ $? != 0 ]; then rm -f "../mk
/ghcconfig_m_vinci7_data1_dietz_ghc_ghc_inplace_bin_ghc-stage2.mk"; exit
1; fi
ghc-config: b���羌
make: *** [../mk/ghcconfig_m_vinci7_data1_dietz_ghc_ghc_inplace_bin_ghc-
stage2.mk] Error 1
}}}
I am using gcc 4.4.6 and have tried both self-built ghc 7.4.2 and ghc
7.6.1 for stage 0.
