On OSX 10.5.8, otool -l libstd.dylib reports:

...
Load command 9
          cmd LC_LOAD_DYLIB
      cmdsize 52
         name /usr/lib/libSystem.B.dylib (offset 24)
   time stamp 0 Wed Dec 31 16:00:00 1969
      current version 0.0.0
compatibility version 0.0.0
Load command 10
      cmd ?(0x00000000) Unknown load command
  cmdsize 0

This causes test/run-pass/mutable-alias-vec.x86 (and probably all others that depend on libstd.dylib) to segfault in dlclose() called by rust_crate_cache::lib::~lib().

I'm digging into macho.ml to see if I can fix it, but I'd be happy if someone got there first. And it's always possible I've misdiagnosed the mutable-alias-vec crash.

http://github.com/jyasskin/rust/commit/d5144998932a3de32c6d0aaa8c5db12a3acf175a seems to fix this, but it doesn't fix mutable-alias-vec.

Nice catch. Strangely I've never see this fault before on OSX, but I'll pick it up once I'm in the office and can cycle on the OSX machine (and check on the contributor paperwork). Thanks!

Allow cast of fat pointers to thin pointers (rust-lang#99)
d7440b9 
Also:
* Correctly cast before dereferencing a thin pointer to a flexible
  struct
* Correct search for trait type in adt (ignore primitive types and
  pointers)
* Correct the choice between thin and fat pointers in codegen_fat_ptr
  and codegen_ty_ref (and rewrite to use mir pointer metadata)

parser: Switch from ansi_term to colored crate

`ansi_term` is no longer maintained and for the simple needs here,
`colored` is much better suited anyway.

Fixes rust-lang#99.
