Starting from your commit r237174, we properly show warning and
the code is not instrumented:
/home/marxin/Programming/testcases/pr68025-2.c:2:9: warning: bad option
-fprofile-arcs to pragma attribute [-Wpragmas]
#pragma GCC optimize("profile-arcs")
^~~
/home/marxin/Programming/testcases/pr68025-2.c:5:1: warning: bad option
-fprofile-arcs to optimize attribute [-Wattributes]
