Explicit linking crashes program

[jesperpedersen]

If you explicit link against coz using

gcc -O0 -fno-omit-frame-pointer -gdwarf-4 -lpthread -lcoz -Wl,-rpath,/usr/local/lib -o threads threads.c

the program will crash with standard execution

./threads 
[libcoz.cpp:100] bootstrapping coz
[inspect.cpp:327] Debug information was not found for any in-scope executables or libraries
Aborted (core dumped)
