New submission from Bohuslav "Slavek" Kabrda: Hi, I'm getting these warnings with -fstrict-aliasing, compiling Python 3.3.2 (compiling with gcc 4.4.7):
/builddir/build/BUILD/Python-3.3.2/Python/ceval.c: In function 'PyEval_EvalFrameEx': /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1006: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1007: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1008: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1009: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1249: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1258: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:1372: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2358: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2362: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2377: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2379: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2388: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2390: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2743: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2745: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2896: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:2909: warning: dereferencing type-punned pointer will break strict-aliasing rules /builddir/build/BUILD/Python-3.3.2/Python/ceval.c:3035: warning: dereferencing type-punned pointer will break strict-aliasing rules This seems to be quite serious, but I'm not a C expert, so I'd like to know whether this is a false positive or this is actually a dangerous bug.
