In truth, I can't , or kind of hard to.
As I mentioned before, this bug only shown in the build system, it has the
most restricted compilation environment. It works fine if I call it in my
machine, but in the rpm build environment, there is no gdb and I cannot
control the compilation options(while, use some method, I can, I could
try).
Could you check if there is no font, what will happen in the code?
At the same time, I will hack the building procedure to provide the info
you want.
