segmentation fault in debug mode

[jwangit]

Can you please shed some lights on this segmentation fault? It disappears in release mode but exists in debug mode. This segmentation fault prompts at this line of code in directory volepsi/tests/Common.h auto r = macoro::sync_wait(macoro::when_all_ready(std::move(t0), std::move(t1)));

The following is the compiling option and the drived result from running ./frontend -u 36.

Can you get a back trace with gdb?

gdb ./out/build/linux/frontend/frontend 
r -u 36
bt

Thanks for replying. I reinstall the dependencies on system other than indicating a location. Then, it is solved.
