Hello list,
while trying to build gcc-4.6.0 on my sparcstation, I got gengtype OOM
killed. That's when I noticed that its RAM usage peaks at 150MB, which is
a bit excessive for parsing a ~500K text file.
The attached patch fixes the leak and gengtype now uses a peak of 4MB
heap. Hopefully I don't do something wrong, since it took me a while to
understand those obstacks...
Thanks,
Dimitris
P.S. I was trying to test gcc on a rare arch (sparc-unknown-linux-gnu) but
unfortunately the sparcstation crashed and burned after this, so I can't
continue the build and report back :-(
