--- Comment #3 from Tobias Grosser <tobias at grosser.es> ---
This was likely not a miscompile, but rather too many threads running in
parallel as we run LNT with -j16 and then allowed each program to create itself
threads without limitation (which resulted in one thread per core and process).
This issue was resolved by hardcoding the number of parallel threads per
process with OMP_NUM_THREADS=2.
