The breakpoint presented in the return statement was not activated while compiling the test with gcc 4.9.2. Added a dummy statement to allow the breakpoint again. 2015-10-14 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/testsuite: * i386-mpx-map.c (foo): Add dummy statement to trigger breakpoint. Change-Id: I5293ca1c7f82a631e1e41cb650c30dd2d09ef3c2 Signed-off-by: Walfred Tedeschi <walfred.tedeschi@intel.com>
