Segmentation fault (core dumped)

[acc_sysC]

I'm trying to instantiate mux multiple times that is also parameterized.

It gives me Segmentation fault (core dumped) error. I can't figure out why this is happening. 

This is the EDA link to the code: https://www.edaplayground.com/x/Et_C

Please guide me.

Thanks

Try running with gdb and check the backtrace

$ gdb <executable name>

gdb> run
(after segfault)
gdb> bt

Your sc_vector sOUT_bit_select is not properly initialized and the sc_vector sIN_segment has the wrong size.

In general I would siggest to use something like this:

	sc_vector<multiplexer<(1<<N)> > bit_mux{bit_mux"",M};
	sc_vector<sc_signal<sc_biguint<(1<<N)>>> sIN_segment{"sIN_segment",M};
	sc_vector<sc_signal<bool> > sOUT_bit_select{"sOUT_bit_select",M};

instead of putting them intit the constructor initializer list.

@Eyck it works! But can you tell me what's the difference between inititializing like this and initializing in the constructor list?

Since the edaplayground code changed I cannot tell since I do not remember what 'like this' was
