I reran just that test and it failed 3 times in a row. Looking back at the logs on this machine it's failed on and off since r11-4323 (run on 23 October).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97090 --- Comment #8 from David Malcolm --- I tested with a cross build on x86_64-pc-linux-gnu with target==powerpc64-unknown-linux-gnu after various fixes for non-determinism (g:f635f0ce87d687b177b734968f18226d50499e75) and I'm not seeing the bogus diagnostic at line 170. I ran 100 iterations (with address-space randomization enabled), via this script: SRC_DIR=$(dirname $1) FILENAME=$(basename $1) rm $FILENAME.* for i in `seq 1 100`; do echo "iteration: $i" ./xgcc -B. -fanalyzer -c $SRC_DIR/$FILENAME -m64 -fdiagnostics-plain-output -fanalyzer -Wanalyzer-too-complex -fanalyzer-call-summaries -fdump-analyzer -fanalyzer-call-summaries -S -fdump-analyzer-supergraph -fdump-analyzer-exploded-graph -fdump-analyzer -fdump-noaddr -fdump-analyzer-exploded-nodes-2 mv $FILENAME.supergraph.dot $FILENAME.$i.supergraph.dot mv $FILENAME.analyzer.txt $FILENAME.$i.analyzer.txt mv $FILENAME.supergraph-eg.dot $FILENAME.$i.supergraph-eg.dot mv $FILENAME.eg.txt $FILENAME.$i.eg.txt mv $FILENAME.eg.dot $FILENAME.$i.eg.dot done md5sum $FILENAME.* | sort | less and got identical md5sums for every iteration of each of the various logs. So perhaps the determinism fixes have removed flakiness from this test. Is anyone still seeing that test failure on any configuration, after g:f635f0ce87d687b177b734968f18226d50499e75 ? (I still need to investigate the other failures reported by Jakub in comment #3)

I think it's due to places in -fanalyzer that iterate though hash_map and hash_set, that are thus implicitly relying on the ordering and thus on specific pointer values. Address-space randomization thus introduces a random element. I've landed some fixes for this in master recently, and am testing some more (sorting every time I use the results of such an iteration).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97090 --- Comment #5 from David Malcolm --- PR 97621 reports it as starting on powerpc64*-linux-gnu with r11-4434, which was a fix for non-determinism in -fanalyzer, so perhaps this is a flaky test that the non-determinism fixes have made fail more reliably (which comment #1 suggests as well).
