Trouble with gdb in rawhide

[Orion Poplawski]

I'm trying to debug a problem with hdf4.2r4 on i586 in rawhide:

$ ./hdfnctest
Testing read/write datasets with unlimited dimensions via SD API 
PASSED
Testing read/write variables with unlimited dimensions via nc API 
*** stack smashing detected ***: ./hdfnctest terminated

but gdb isn't being very helpful:

I'm at a loss.  What is triggering the initial SIGTRAP?  Why don't I get 
to main?
