This one is part of initialization done once well before the loop over the tests, so I don't think it can interfere in any way (and my "ps fauxww" log doesn't show it around). > However, I also > don't see at least parts of the rest of the script that you quote, so > maybe I'm looking at the wrong version (looking at trunk) or you have > added debug statements, so maybe yours has more such stray asynchronous > lists. Yes my quote is from my heavily instrumented run_all.sh. The svn clean run_all.sh will exhibit the random fail with the very same error message in gcc/testsuite/ada/acats/acats.log so the instrumentation doesn't change the failure mode. Thanks for your help, Laurent
