Subject: * dwarf.c (display_debug_names): Initialize hash_prev.
X-Git-Tag: binutils-2_29_1~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ab0462915cae36d5af2315540745f348603ad61f;p=thirdparty%2Fbinutils-gdb.git

* dwarf.c (display_debug_names): Initialize hash_prev.

gcc-4.3.0 warns that it may be used uninitialized.  It takes a look
and a half at the code to understand that it's false.

Import from mainline.
