Silence maybe-uninitialized warning in dwarf2read.c
I upgraded to Fedora 30 recently. It includes GCC 9, which gives a
warning for dwarf2read.c:
../../binutils-gdb/gdb/dwarf2read.c:16103:24: warning: ‘discr_offset’ may be used uninitialized in this function [-Wmaybe-uninitialized]
This patch fixes the problem by initializing discr_offset.
Tested by rebuilding.
