That's odd, since our PGO builds don't use nearly that much memory. I can build a PGO Firefox on a 32-bit WinXP box with 2GB of ram without any thrashing. The linker tops out at a little over 1GB of memory usage while linking libxul (using VC2005 or VC2010, with VC2009 I run out of memory).

"Lots" being relative. The linker just requires the full 4 gigs of address space. Simply using /3GB on a 32 bits OS isn't sufficient. > I don't know if we'd seen similar problems with Breakpad symbols. > > Wan-Teh > > -- > Chromium Developers mailing list: chromium-dev@googlegroups.com > View archives, change email options, or unsubscribe: > http://groups.google.com/group/chromium-dev > -- Chromium Developers mailing list: chromium-dev@googlegroups.com View archives, change email options, or unsubscribe: http://groups.google.com/group/chromium-dev

It's Visual C++ 2005. (The official build does whole program optimization and must be done on a 64-bit Windows machine with lots of memory.) I don't know if we'd seen similar problems with Breakpad symbols.

I don't know the answer to the rest of your question, but I think we're using a machine with >=24gb of ram to do the PGO build. > VC2010b2 works fine, > and doesn't seem to exhibit the same problems, but of course it's not > out of beta yet. > > Thanks for any info, > -Ted > > -- > Chromium Developers mailing list: chromium-dev@googlegroups.com > View archives, change email options, or unsubscribe: >http://groups.google.com/group/chromium-dev > -- Chromium Developers mailing list: chromium-dev@googlegroups.com View archives, change email options, or unsubscribe: http://groups.google.com/group/chromium-dev
