AddressSanitizer: alloc-dealloc-mismatch (operator new [] vs free)
When compiling native node dependencies with -fsanitize=address
to enable AddressSanitizer, there appears to be warnings originating from lmdb-js.
For example, when using a project that uses parcel
's watch mode:
$ CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" \
CXXFLAGS="-g -fsanitize=address -fno-omit-frame-pointer" \
LDFLAGS="-fsanitize=address" \

yarn install

The trace suggests that when creating compressed values, operator new[]
is used:
https://github.com/kriszyp/lmdb-js/blob/6e4146d635a66b360f6b94f746f948f2a0b2bf3d/src/compression.cpp#L123-L125
but when freeing it, free
is used
https://github.com/kriszyp/lmdb-js/blob/6e4146d635a66b360f6b94f746f948f2a0b2bf3d/src/writer.cpp#L297-L299 In this context, I would assume that there is no immediate problem as it's just an array, but with a more complex type this would result in the destructor not being ran.
Is this undefined behavior which should be fixed, or just something for me to ignore in the results?
