crash of h5dump of H5MM.c in function H5MM_memcpy

[NigelX]

Hi
I found an crash error.

System info：
Ubuntu 20.04 : clang 10.0.0 , gcc 9.3.0

hdf5 version 1.13.0 ,git branch development

---

Verification steps：
1.Get the source code of hdf5
2.Compile the hdf5

$ cd hdf5
$ mkdir build && cd build
$ cmake ../ -DCMAKE_C_COMPILER=clang  -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_FLAGS="-fsanitize=address" -DCMAKE_CXX_FLAGS="-fsanitize=address"
$ make -j 32

3.run h5dump

$ cd bin
$ mkdir crashtest_dir
$ ./h5dump -r -d crashtest_dir/data poc

poc.zip
