Clock sharing seg fault insert_parent(int)

[mzio]

I have a hierarchical design and I have a problem with the clock signal.

Consider top module A where the clock is generated, a module B inside of it with sc_in<bool> clk port bound to sc_clock signal.

Inside of module B I instantiate other modules, some of them with sc_in<bool> clk port.

When I try to connect the clock port of the modules inside B I get a segmentation fault, that's gdb output: 

Thread 2 "ctrl_interface" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff6789700 (LWP 23216)]
0x000000000042bb93 in sc_core::sc_port_base::insert_parent(int) ()

During the debug, if I remove the clock port of the modules inside B I don't get any segmentation fault.

Every clock port in this hierarchical design is sc_in<bool>, not sc_in_clk.

Any suggestions?

Hi, you can debug segmentation fault with debugger. Most likely you have some typo with implicit cast in your program.

Fortunately segfaults are easy to debug!
