Description (last modified by igloo)

I downloaded ghc-6.6 source and built it from ghc-6.4.2 (which I previously built on this same machine). The newly built binary doesnt work.

root@discover# ghc-6.6
Segmentation fault

Upon investigation it looks like the stage1 compiler doesnt crash but the stage2 compiler does:

root@discover# compiler/stage1/ghc-6.6
ghc-6.6: missing -B<dir> option

From talking with the submitter it seems to not be a compilation problem (as he also gets it with the binary dists), and it happens only with -threaded.

[Check with sysconf _POSIX_THREAD_CPUTIME is available before we try to use it.
Ian Lynagh <>**20070116012907
 Calling clock_gettime(CLOCK_THREAD_CPUTIME_ID,_) regardless was
 causing a segfault (trac #1030).
