From 903f334ef06fbec28d23b7c8ea3c79cacc1da14f Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Tue, 27 May 2014 10:25:27 +0200 Subject: [PATCH] readelf: Skip section if name is NULL in print_debug. Don't crash and burn when a section doesn't have a name (possibly invalid ELF file string table). Just try the next section instead of calling strcmp on NULL.
