I used gcc 3.3.1 with -O2 -fno-strength-reduce -fomit-frame-pointer.

I got that part. But AFAICS, when strtol(env,NULL,0) is used to set

The string may begin with an arbitrary amount of white space (as

Hi Mark,
I think I've seen this one before, and it was due to an environment

Oh! I also get worse performance with 3.3.2, ~13 vs. 17MBps on
