Peter,
Thanks for the hints.

It shows the register values, which are not necessarily the
arguments to memcpy(), apparently not in this case.
The "guilty" line of code
HDmemcpy(tgath_buf,buf+off[curr_seq],curr_len);
translates into (due to macro "#define HDmemcpy(X,Y,Z)
memcpy((char*)(X),(const char*)(Y),Z)")
memcpy((char*)(tgath_buf),(const char*)(buf+off[curr_seq]),curr_len);
and
(dbx) p tgath_buf
tgath_buf = 0x9f5c4f0
(definitely not NULL)
We've also asked for help at help at hdfgroup.org regarding the HDF5
package.
This is under Solaris 10 x86, using the latest Sun Studio
compiler/tools.
