Subject: Mac OS X 10.1.4 started to consume 150MB+ virtual memory
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=b5d3f31f7e101c9ef1c84c388e7036ccb0b99518;p=p5sagit%2Fp5-mst-13.2.git

Mac OS X 10.1.4 started to consume 150MB+ virtual memory
while trying to -O3 optimize B.c.  (A bit weird since
10.1.4 used to work fine, and nothing has changed in
ext/B/..., but the overoptimization was repeatable.)
