ERROR: System recieved a signal named SIGSEGV and the program has to stop immediately!
This signal was generated when a program tries to read or write outside the memory that is allocated for it, or to write memory that can only be read.
Possible cause of this problem may be: 1) the depth setting of pointer type argument is much larger than it needed; 2)insufficient depth of array argument; 3)null pointer etc.
Current execution stopped during CodeState = .
You can search CodeState variable name in apatb*.cpp file under ./sim/wrapc dir to locate the position.

my vivado hls is 2018 and the xfopencv is also 2018 version.
when i run the example medianblur in vivado hls ，i pass the simulation and sythesis but fail the RTL cosimulation， the error is：
source xsim.dir/median_blur_accel/xsim_script.tcl
xsim {median_blur_accel} -autoloadwcfg -tclbatch {median_blur_accel.tcl}
Vivado Simulator 2018.3 Time resolution is 1 ps source median_blur_accel.tcl
