GNU C++ version 4.2.1 20070719 [FreeBSD] (amd64-undermydesk-freebsd)
compiled by GNU C version 4.2.1 20070719 [FreeBSD].
Also occurs on 8.1-PRERELEASE from early June.
>Description:
The compilation of .../JavaScriptCore/interpreter/Interpreter.cpp
in ports/devel/qt4-script loops, with cc1plus slowly eating memory
until it hits ulimit or runs out of swap, when compiled with
'-g -O2 -march=nocona'
Removing either '-g' or '-march-nocona' causes the compilation to
succeed normally in 30 seconds or less. With both specified,
I saw the cc1plus VSZ grow to over 1.5GB and use over 70 minutes
of CPU before I gave up watching.
