Source showing problem
I'm getting an incorrect "dereference of undefined pointer value" warning using
checker-273 that didn't occur with checker-272.
Running "scan-build c++ -c <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - crash on input from C++ frontend"
href="show_bug.cgi?id=48">bug48</a>.cpp" produces 2 incorrect warnings.
The analysis takes a path where "token->use48" is true in the first "if" and
false in the second "if" (and vice-versa) but that's not possible.</pre>
