 Dix says this was filed as Apple Radar 3042899, quite some time ago.  
 In summary:
 
 The compiler is not really hanging, just taking a very long time 
 (hours).   The problem is specific to -Os.  A workaround for released 
 compilers is to add -fno-gcse, or use -O2 instead of -Os.  
 -fno-schedule-insns will also help.
 
 It looks like later compiler releases (3.3, 3.4, the next Apple 
 compiler release) will have the performance bottlenecks improved, down 
 to sane numbers (like 10 minutes, with no workarounds, or 1 minute with 
 -fno-schedule-insns in 3.3, and better in 3.4).

 This is most likely a bug specific to Apple's compiler.  Could you file
