[AGENT++] Is it possible to return error from RowStatus set function?

[dennis w]

It seems to me that we cannot return error code  
mibTableRowStatus::set(const Vbx& vb)  when creating a row at dynamic table. 
Here is what I got from the   "cmd_exe_mib" example.

In the cmd_exe_mib.cpp, we have

int cmdExecutionCmdRowStatus::set(const Vbx& vb)
{
...
       if (vb.get_value(l) != SNMP_CLASS_SUCCESS)
                return SNMP_ERROR_WRONG_TYPE;
...

But if we actually return this error "SNMP_ERROR_WRONG_TYPE".  The agent 
will just lock. You have to kill -9 to kill the process (at linux).

The stack trace is following,

#0  0x001ac7a9 in __lll_mutex_lock_wait () from /lib/tls/libpthread.so.0
#1  0x001a9797 in _L_mutex_lock_28 () from /lib/tls/libpthread.so.0

Is that something we should not do , or it is possible a bug?
