Comment (by kgardas):

 Honestly it's quite strange that w/o -threaded this works for you, since:
 {{{
 karel at silence:/tmp/ttt$ ls -la
 total 6392
 drwxr-xr-x   2 karel    karel        178 Jul 31 15:58 .
 drwxrwxrwt  25 root     sys         2823 Jul 31 15:58 ..
 -rwxr-xr-x   1 karel    karel    3261384 Jul 31 15:58 test
 karel at silence:/tmp/ttt$ mkdir test
 mkdir: Failed to make directory "test"; File exists
 karel at silence:/tmp/ttt$
 }}}
 and test also shows the same behaviour:
 {{{
 karel at silence:/tmp/ttt$ ./test
 test: test: createDirectory: already exists (File exists)
 karel at silence:/tmp/ttt$
 }}}
 anyway, if I rename test -> textx, then I get:
 {{{
 karel at silence:/tmp/ttt$ ./testx
 Starting Subprocess
 testx: ghc: createProcess: runInteractiveProcess: exec: does not exist (No
 such file or directory)

 karel at silence:/tmp/ttt$
 }}}
 single-threaded fails in the way like yours:
 {{{
 karel at silence:/tmp/ttt$ ./test-st
 Starting Subprocess
 ghc: no input files
 Usage: For basic information, try the `--help' option.
 Exit code: ExitFailure 1

 karel at silence:/tmp/ttt$
 }}}
 anyway, if I modify test to point directly to ghc (full path), then it
 works also with -threaded
 {{{
 karel at silence:/tmp/ttt$ ghc -threaded ../test.hs -o test-thr
 karel at silence:/tmp/ttt$ ./test-thr
 Starting Subprocess
 ghc: no input files
 Usage: For basic information, try the `--help' option.
 Exit code: ExitFailure 1

 karel at silence:/tmp/ttt$
 }}}
 my guess is that environment handling is kind of fishy on Solaris. We also
 do have few tests in this domain failing.
