Subject: testsuite: Fix overflow in gcc.dg/vect/pr116125.c
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=156c3ee6a9095c5ec6fc10d837fe3ae2291ad8a8;p=thirdparty%2Fgcc.git

testsuite: Fix overflow in gcc.dg/vect/pr116125.c

The test ends up writing a byte beyond bounds of the buffer, which gets
trapped on some targets when the test is run with
-fstack-protector-strong.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/pr116125.c (mem_overlap): Expand A to 10 members.
