ex_h5ex_t_vlen.c bug on windows compiled and run with cl - 1.14.6

In the file HDF5Examples/C/H5T/ex_h5ex_t_vlen.c, compiled and run with VS2022 and version 1.14.6, there is a runtime error at line 78: status = H5Dvlen_reclaim(memtype, space, H5P_DEFAULT, wdata);

Error Description
The immediate cause of the error is the execution of the H5Dvlen_reclaim function, which is responsible for reclaiming memory allocated for variable-length data. The rdata variable, which is passed to this function, has an invalid value (0xcccccccccccccccc), indicating that it was not properly initialized or allocated before being used.

Application runs without error. It seems to do so if I comment out line 78, the H5Dvlen_reclaim function.

**Platform (please complete the following information)**
- HDF5 version (if building from a maintenance branch, please include the commit hash)
1.14.6
- OS and version
