Subject: crx string overflow warning
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e95b887f85a192eb1597cd5d358673520029ad14;p=binutils-gdb.git

crx string overflow warning

gcc8 complains wrongly about the buffer not being large enough, at
least at -Og optimization.

	* crx-dis.c (getregliststring): Allocate a large enough buffer
	to silence false positive gcc8 warning.
