Subject: gdb, dwarf: add assert to dwarf2_get_pc_bounds
X-Git-Tag: binutils-2_42~341
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06740cf11f601c6a5a0f3807f37aaac31d13a542;p=thirdparty%2Fbinutils-gdb.git

gdb, dwarf: add assert to dwarf2_get_pc_bounds

In dwarf2_get_pc_bounds we were writing unchecked to *lowpc.  This
commit adds a gdb_assert to first check that lowpc != nullptr.
