SUMMARY: AddressSanitizer: 28614 byte(s) leaked in 36 allocation(s).

That file you sent (pov.zip) contained what appears to be an HDF5 file (pov).
When I attempted to dump it using the h5dump command, I got the error below.
This is clearly a malformed HDF5 file. Can you describe how the file was created?

h5dump pov.nc
h5dump error: internal error (file h5dump.c:line 1518)

As mentioned previously (#2665 (comment)), I found the error when running ncdump on the pov file not while running h5dump. Have you tried to run ncdump on the pov file?
The pov file was generated by running a fuzzer on ncdump.

[DennisHeimbigner]

For historical reasons, when our library encounters an unrecoverable error, then it does
not always reclaim allocated memory, hence there can be memory leaks in that case.
In the event that there are not errors, we test and fix any memory leaks.
The pov file you sent does not appear to be a legitimate netcdf-4 or hdf5 file, so we get
errors, which implies potential memory leaks.
So the real problem, from my point of view, is that you somehow managed to create a
malformed file. If you did it somehow using the netcdf library, then that is the problem
I need to fix.

This issue has been fixed in commit b1431067c ("fix memory leak", 2026-03-15). The fix adds proper cleanup in nc4_nc4f_list_add() in libsrc4/nc4internal.c: when nc4_grp_list_add() fails, the code now frees h5->hdr.name, h5->alldims, h5->alltypes, h5->allgroups, and h5 itself before returning the error, preventing the indirect leaks through ncindexnew → NC_hashmapnew from being orphaned. This issue can be closed.

Closing as complete, thanks!
