Do we really want to support this large of a repeat count? > Ugh**2. If I'm not mistaken, this will create an executable with 4 GB of static data in it. I think we should but a sane limit on the value. Btw, I'm sitting at 51879 sgk 1 122 0 1302M 1304M CPU1 1 14:17 93.41% as 51878 sgk 1 -8 0 17684K 12924K pipewr 0 7:58 48.78% f951 in top(1). So, it memory grows to rough 4GB, then it will take about an hour to compile this program. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31244
