I'm trying to pin down why unit tests fail for the 5.1, 5.2 and 5.3 series of the (m)aria engine. My build tool runs 'make test-unit' and the following errors appear. The build tool does strip out some environment variables, but running from bash directly doesn't change anything. Can anyone provide pointers? Thanks (This is from MariaDB 5.1.62) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 73/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e4096 -K ' (loop iteration 8.) at line 316 (errcode: 256, test: 83) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 85/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e8192 -K ' (loop iteration 9.) at line 316 (errcode: 256, test: 85) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e16384 -E16384 -K -L ' (loop iteration 10.) at line 316 (errcode: 256, test: 87) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 238/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e4096 -K -S' (loop iteration 8.) at line 316 (errcode: 256, test: 242) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e8192 -K -S' (loop iteration 9.) at line 316 (errcode: 256, test: 244) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 246/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e16384 -E16384 -K -L -S' (loop iteration 10.) at line 316 (errcode: 256, test: 246) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 399/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e4096 -K -M' (loop iteration 8.) at line 316 (errcode: 256, test: 401) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e8192 -K -M' (loop iteration 9.) at line 316 (errcode: 256, test: 403) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e16384 -E16384 -K -L -M' (loop iteration 10.) at line 316 (errcode: 256, test: 405) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 557/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e4096 -K -M -T' (loop iteration 8.) at line 316 (errcode: 256, test: 560) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e8192 -K -M -T' (loop iteration 9.) at line 316 (errcode: 256, test: 562) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 564/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e16384 -E16384 -K -L -M -T' (loop iteration 10.) at line 316 (errcode: 256, test: 564) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 716/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e4096 -K -M -T -C' (loop iteration 8.) at line 316 (errcode: 256, test: 719) [16:34:05] ../storage/maria/unittest/ma_test_all-t ..................... 721/830 Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e8192 -K -M -T -C' (loop iteration 9.) at line 316 (errcode: 256, test: 721) Failed test '../storage/maria/unittest/../ma_test2 -s -htmp -m10000 -e16384 -E16384 -K -L -M -T -C' (loop iteration 10.) at line 316 (errcode: 256, test: 723) [16:34:05] ../storage/maria/unittest/ma_test_all-t .....................
