But stime should always be below rtime due to the calculation done by scale_stime() which roughly sums up to: stime = (stime / stime + utime) * rtime So this shouldn't happen.

This seems to be problem with dynamic ticks as you told that your application is kernel compilation, so we utilize lot of cpu time in user-space. Anyway we should handle utime == 0 situation on scaling code. We work well when rtime & stime are not big (variables and results fit in 32 bit), otherwise we have that stime bigger than rtime problem. Let's try to handle the problem by below patch.
