Hi,
I call H5Rget_name() twice, once to get the length of the object's name,
the second time to get the actual name (as described at
http://www.hdfgroup.org/HDF5/doc/RM/RM_H5R.html#Reference-GetName).
In my initial version I passed NULL as the name buffer and a size of 0
-- that failed an assert on the name parameter. My next version had a
zero-length character array as the name buffer (and size still as 0).
That resulted in a thrashed stack, as in H5G_get_name_by_addr() from
H5Gname.c there is an HDstrncpy(name, "/", 2); which is done regardless
of the buffer size.
H5G_get_name_by_addr() allows for a NULL name -- shouldn't H5Rget_name()
also allow its name parameter to be NULL ??
And then the buffer size should be checked before the initial path
separator is copied.
Regards,
Dave
