Strange failures in directory/

[Simon Peyton Jones]

I'm getting these validate failures from "sh validate -fast":


Unexpected failures:

   ../../libraries/directory/tests  getHomeDirectory001 [exit code non-0] (normal)
      .. and about 20 more similar complaints ...

The failure report is this:

Compile failed (status 256) errors were:

[1 of 1] Compiling Main             ( getHomeDirectory001.hs, getHomeDirectory001.o )

*** unexpected failure for getHomeDirectory001(normal)

BUT if I "cd libraries/directory/tests", and say "make TEST=getDirContents001", I get no failures.

Here is a clue.  If I "cd testsuite/tests" and say "make TEST=getDirContents001", I get this:


=====> getHomeDirectory001(normal) 4288 of 4405 [0, 0, 13]

cd ../../libraries/directory/tests && '/5playpen/simonpj/HEAD-2/inplace/bin/ghc-stage2' -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts -fno-warn-tabs -fno-ghci-history -o getHomeDirectory001 getHomeDirectory001.hs    >getHomeDirectory001.comp.stderr 2>&1

cd ../../libraries/directory/tests && ./getHomeDirectory001    </dev/null >getHomeDirectory001.run.stdout 2>getHomeDirectory001.run.stderr

=====> getHomeDirectory001(normal) 4301 of 4405 [0, 0, 13]

cd ../../libraries/directory/tests && '/5playpen/simonpj/HEAD-2/inplace/bin/ghc-stage2' -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts -fno-warn-tabs -fno-ghci-history -o getHomeDirectory001 getHomeDirectory001.hs    >getHomeDirectory001.comp.stderr 2>&1

cd ../../libraries/directory/tests && ./getHomeDirectory001    </dev/null >getHomeDirectory001.run.stdout 2>getHomeDirectory001.run.stderr

Note that it gets compiled TWICE.  This is likely to cause problems when multi-threading.

Anyone have any ideas?
