Date: Wed, 02 May 2007 12:49:06 +0100 From: Andy Green <andy@...mcat.com> To: lkml <linux-kernel@...r.kernel.org> Subject: [PATCH] scripts/basic/fixdep segfault on pathological string-o-death build scripts: fixdep blows segfault on string CONFIG_MODULE seen The string "CONFIG_MODULE" appearing anywhere in a source file causes fixdep to segfault. This string appeared in the wild in the current mISDN sources (I think they meant CONFIG_MODULES). But it shouldn't segfault (esp as CONFIG_MODULE appeared in a quoted string).
