hi, there seems to be some issue with the newish selection code when compiling numpy with the ICC compiler. See this issue: https://github.com/numpy/numpy/issues/4836
I cannot reproduce the problem even when compiling with ICC myself. I have also tried valgrind and GCC's undefined behavior sanitizer without any results. Can somebody with debugging experience please try the posted testcase and if it is reproduce-able provide the information needed to fix this. It should also affect 1.8.0 if you replace the percentile call with np.partition(imc[i], (0, 1, 1027603, 1027604)) I would need a backtrace, the current register state, the local variables, disassembly and ideally the few steps until the crash/wrong result with variable state.
