Validate of GHC HEAD freezes on FreeBSD

[Kazu Yamamoto ( 山本和彦 )]

Hello,

The "validate" script against GHC HEAD freezes on FreeBSD 9.1.
After sync-all, I did as follow:

----------------------------------------------------------------
% config_args="--with-iconv-includes=/usr/local/include --with-iconv-libraries=/usr/local/lib --with-gmp-includes=/usr/local/include --with-gmp-libraries=/usr/local/lib --with-gcc=/usr/local/bin/gcc47" CPUS=10 sh validate
----------------------------------------------------------------

This stopped quickly due to this problem:
	http://hackage.haskell.org/trac/ghc/ticket/7592

Then I executed "validate" with "--no-clean" again.

----------------------------------------------------------------
% config_args="--with-iconv-includes=/usr/local/include --with-iconv-libraries=/usr/local/lib --with-gmp-includes=/usr/local/include --with-gmp-libraries=/usr/local/lib --with-gcc=/usr/local/bin/gcc47" CPUS=10 sh validate --no-clean
----------------------------------------------------------------

GHC could be compiled and tests started. But this resulted in:

----------------------------------------------------------------
cd ../../libraries/base/tests && '/usr/home/kazu/work/ghc/bindisttest/install   dir/bin/ghc' -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts -fno-ghci-history -o qsemn001 qsemn001.hs    >qsemn001.comp.stderr 2>&1
cd ../../libraries/base/tests && ./T5962    </dev/null >T5962.run.stdout 2>T5962.run.stderr
cd ../../libraries/base/tests && ./5943    </dev/null >5943.run.stdout 2>5943.run.stderr
cd ../../libraries/base/tests && ./T7034    </dev/null >T7034.run.stdout 2>T7034.run.stderr
cd ../../libraries/base/tests && ./qsem001    </dev/null >qsem001.run.stdout 2>qsem001.run.stderr
cd ../../libraries/base/tests && ./qsemn001    </dev/null >qsemn001.run.stdout 2>qsemn001.run.stderr

Wrong exit code (expected 0 , actual 9 )
Stdout:

Stderr:

*** unexpected failure for Chan002(normal)
----------------------------------------------------------------

And waiting for something forever.

Does anyone understand what happened?

Note that I can build GHC HEAD by typing "gmake" (v3.82 installed by
the ports system) twice.

This is a serious problem for us since we want to merge our code to
GHC HEAD. "validate" against GHC with our code on Linux and Mac passed
so far. But "validate" against even vanilla GHC freezes.

P.S.

On FreeBSD, I applied the following patch for validate since
unused-but-set-variable is not available.

diff --git a/mk/validate-settings.mk b/mk/validate-settings.mk
