See #38015 for why we re-enabled asm, and see comment:ticket:38015:40 where I tested all systems I had access to and verified that they worked with and without asm, except for the few new model Mountain Lion systems that were experiencing the bug in that ticket, which required asm to be on. I did not have a Tiger i386 test machine set up however so I did not test that. And my testing was with 1.0.1d, and you're now using 1.0.1e. #33741 was with 1.0.1. The assembly code no doubt changes with each release.
Which specific Intel Mac model do you have? Any particular reason you're still running Tiger on it? All Intel Macs can be upgraded to at least Snow Leopard, which I feel is a better OS in most every way, and by upgrading you should encounter fewer problems building ports (though I can't guarantee that would resolve this particular issue).
