I will retests when i spot it in one of the repos (right now i only see 1645 and 1642).
can you also elaborate on how to "print 'sb' structure from frame 4". I am linux noobie.

I think that the problem is fixed so I don't need the further feedback if everything is fine. In gdb, you can select the stack frame with 'frame <number>' and print the contents of a local variable using the print command like 'print *sb' (the * means the contents of the structured behing the pointer, without this, just the pointer - memory address is printed).
