>Description:
	A recently built cross compiler for arm loops while compiling
	several of groff's files in gnu/usr.bin/groff/src/libs/libgroff.

	I observed it using 511 CPU minutes on cmap.cpp, and 4+ on
	color.cpp.

	The compiler is:

stegg: {6} /usr/tools/bin/arm--netbsdelf-g++ --version
arm--netbsdelf-g++ (GCC) 3.3.3 (NetBSD nb2 20040502)

>How-To-Repeat:
	Try to cross-build libgroff for arm with a recently updated
	toolchain.

>Fix:
	This works as a workaround for this directory, but this should
	be fixed properly by finding and fixing the gcc optimizer bug:
