segfault/stack smashing attempt with h4h5tools v 2.1 and libhdf5 1.8.5.1

Hi list,
one of our users has reported an odd problem with the h4toh5 tool. On a 64bit machine h4toh5 fails with
*** stack smashing detected ***: h4toh5 terminated
Aborted
on 32bit it simply segfaults. h4h5tools pass the supplied test suite. The older version of the h4h5tools works fine. On 32bit, I get the following backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x08073862 in H4toH5check_objname_in_use (h4toh5id=1684549234, h5par_path=0x0,

(gdb)

I had a look at the code but couldn't see any obvious problems. Does anyone have any suggestions?

Cheers

Hi Magnus,

Could you please send the HDF4 file to help@hdfgroup.org? We will take a look. And which version of h4h5tools are you using?

Thank you!

Elena
