By no means a Pro*C supporter (never mind expert), but I could not see anything that is glaringly wrong.

Some random thoughts on what could be causing it

• threading and running out of stack space
• logic error when constructing and populating the array structs containing the bound variable values and the subscripting it out of range (e.g doing a loop using a COUNT property of class as stop value instead of COUNT-1 as the enum starts at 0 and not 1)
• something screwy in 64bit HPUX's memory management when running a 32bit process (not impossible, I have seen some weird bugs in Unix kernels)

But before looking at OCI or the kernel for a bug, I would look at my code first... Do something simple like adding a few printf's before the UPDATE and dump the SQL statement and bind variable values to a text log and make sure that I'm passing valid stuff to the OCI.
