TagLib::offset_t is off_t on POSIX, which is a 32-bit signed type on 32-bit platforms built without _FILE_OFFSET_BITS=64 (e.g. Debian i386). The RF64 support introduced in 2.3.2 clamps chunk sizes with std::min<offset_t>(size, 0xffffffff): with a 32-bit offset_t the constant converts to -1 and becomes the result, so chunkDataSize() returns 4294967295 and the WAV/AIFF/RIFF parsers misbehave. In read(), a declared size above 2 GiB likewise turns negative before the clamping check. Perform the clamping in 64-bit types instead. Fixes the test suite failures (TestRIFF, TestWAV, TestAIFF) observed on Debian i386. The same clamp in WAV::Properties is fixed as well.
