Subject: timeout in mmo_get_symbols
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=31e43bfffbc585a59d07f21f191317a714476e38;p=binutils-gdb.git

timeout in mmo_get_symbols

Fix mmo_get_byte to return a fail-safe value, not just on the first
call with a read error but on subsequent calls too.

	* mmo.c (mmo_get_byte): Return the fail-safe value on every
	call after a read error.
