test case
Sorry the example is dumb, the original code had some logic between the
conditionals.
I get:
scan-build: Using '/usr/pkg/bin/clang-4.0' for static analysis
test.c:18:6: warning: Dereference of null pointer (loaded from variable 'a')
*a = 12;
~ ^
1 warning generated.
scan-build: 1 bug found.
scan-build: Run 'scan-view /tmp/scan-build-2017-04-18-203149-15179-1' to
examine bug reports.
