I get a segfault with 20060530 when building xstow that I didn't get with 20060508. The segfault doesn't show up when I run g++ on the preprocessed file but pinskia pointed out that I should use --param ggc-min-expand=0 --param ggc-min-heapsize=0, and indeed, when I add --param ggc-min-expand=0 I see it - but also with 20060508.
It turns out that this segfault was introduced sometime between 20060325 and 20060419. (And, in fact, compiling xstow with 20060419 also segfaults, just not 20060508.)
