Infinite output port number for hierblock2 causes exception
Status: new
| Reported by: | dominik | Assigned to: | jcorgan |
|---|---|---|---|
| Priority: | normal | Milestone: | to-be-decided |
| Component: | gnuradio-core | Version: | 3.1svn |
| Keywords: | hierblock2 iosignature maxstreams | Cc: | |
The following code throws a standard exception:
gr.hier_block2.__init__(self, "static_tx_control", gr.io_signature (1,-1,gr.sizeof_float),...))
This is a bug in gr hier block2 detail at lines 37 and 38.
37 d_inputs(owner->input_signature()->max_streams()), 38 d_outputs(owner->output_signature()->max_streams())
A specification of maximum stream number equal -1 ( == IO_INFINITE ) leads to std::vector allocation with size=-1, therefore the std::vector implementation throws std::bad_alloc.
The most simple solution would be a value range check to at least give a more readable error message, though I consider this to be a design error in conjunction with the problem specified in ticket #161.
