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.
