2.54, 2.55

The summary contains two separate test cases, GHC 7.4.1.20120406, looks like it's a problem with handling of some literals

<< gets stuck in infinite lopp >>

Lots of other literals also have this problem. The infinite looping version seems to get stuck determining the gcd, gdb backtrace gives this:

#0  0x000000010cebf042 in __gmpn_gcd_1 ()
#1  0x000000010ceb8d81 in integer_cmm_gcdIntzh ()

dtruss lots of these:

sigreturn(0x7FFF6E530220, 0x1E, 0x11104D5C0)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x7FFF6E530220)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x11104D5C0)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x7FFF6E530220)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x11104D5C0)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x7FFF6E530220)		 = 0 Err#-2
sigreturn(0x7FFF6E530220, 0x1E, 0x11104D5C0)		 = 0 Err#-2

The linux version doesn't seem to have this problem.
