Update of /cvsroot/sbcl/sbcl/src/code
In directory usw-pr-cvs1:/tmp/cvs-serv23783/src/code

Modified Files:
	debug.lisp 
Log Message:
0.7.4.10:
	fixed dumb error in debug.lisp/0.7.4.9 modifications (spotted
		by eagle eyes of CSR)
	Since I still don't have a good fix for the bogus "error in
		constant folding" in %WITH-ARRAY-DATA-MACRO (e.g. in
		compiling src/compiler/dump.lisp)...
	...logged it as bug
	...downgraded it from full WARNING to STYLE-WARNING to make the
		bug less painful
	...removed :IGNORE-FAILURE-P from src/compiler/dump and
		src/code/cold-init entries in build-order.lisp-expr,
		since the downgrade to STYLE-WARNING makes them
		unneeded
