2019-09-03Silence -fsanitize=object-size in --enable-optimized buildsStephan Bergmann
<http://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html#available-checks> (as of recent LLVM trunk towards LLVM 10) states: "-fsanitize=object-size: An attempt to potentially use bytes which the optimizer can determine are not part of the object being accessed. This will also detect some types of undefined behavior that may not directly access memory, but are provably incorrect given the size of the objects involved, such as invalid downcasts and calling methods on invalid pointers. These checks are made in terms of __builtin_object_size, and consequently may be able to detect more problems at higher optimization levels." A `make check screenshot` with --enabled-optimized runs into two such issues that were not diagnosed with --disable-optimized, in both cases because a struct with an "idiomatic trailing dynamic array member" (statically declared to be an array of size 1) is allocated without any space for that array member, as the dynamic array size is 0 in the specific case: * For > [CUT] sc_ucalc > cppu/source/uno/copy.hxx:46:19: runtime error: member access within address 0x6020001aaa70 with insufficient space for an object of type 'uno_Sequence' (aka '_sal_Sequence') > 0x6020001aaa70: note: pointer points here > 2b 00 80 6a be be be be be be be be 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > ^ > #0 in cppu::allocSeq(int, int) at cppu/source/uno/copy.hxx:46:19 (instdir/program/libuno_cppu.so.3 +0x41f03f) > #1 in uno_type_sequence_reference2One at cppu/source/uno/sequence.cxx:813:20 (instdir/program/libuno_cppu.so.3 +0x41f03f) [...] the call to pNew = allocSeq( 0, 0 ); in uno_type_sequence_reference2One is inlined, so sal_uInt32 nSize = calcSeqMemSize( nElementSize, nElements ); in allocSeq is known to be too small. * For > testSignatureLineODF::TestBody finished in: 2044ms > engine-gpg.c:302:6: runtime error: member access within address 0x604001f24f10 with insufficient space for an object of type 'struct arg_and_data_s' > 0x604001f24f10: note: pointer points here > 6e 01 00 26 be be be be be be be be be be be be be be be be be be be be be be be be be be be be > ^ > #0 in add_data at workdir/UnpackedTarball/gpgmepp/src/engine-gpg.c:302:6 (instdir/program/libgpgme.so.11 +0x120c2b) [...] > make[1]: *** [solenv/gbuild/CppunitTest.mk:114: workdir/CppunitTest/xmlsecurity_signing.test] Error 1 the a = malloc (sizeof *a - 1); is apparently detected to be too small only with optimization enabled. In both cases, the solution is to operate on the too-small dynamically allocated object via a reinterpret_cast'ed pointer to some newly introduced "struct prefix" type.

...warning about (for now only) functions and variables with external linkage that likely don't need it. The problems with moving entities into unnamed namespacs and breaking ADL (as alluded to in comments in compilerplugins/clang/external.cxx) are illustrated by the fact that while struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { struct S2: S1 { int f() { return 1; } }; int f(S2 s) { return s.f(); } } int main() { return f(N::S2()); } returns 1, both moving just the struct S2 into an nunnamed namespace, struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { namespace { struct S2: S1 { int f() { return 1; } }; } int f(S2 s) { return s.f(); } } int main() { return f(N::S2()); } as well as moving just the function f overload into an unnamed namespace, struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { struct S2: S1 { int f() { return 1; } }; namespace { int f(S2 s) { return s.f(); } } } int main() { return f(N::S2()); } would each change the program to return 0 instead.
