ASAN:SIGSEGV
|
==10706==AddressSanitizer: while reporting a bug found another one.Ignoring.
|
To reproduce:
git clone https://github.com/elenst/rqg --branch mdev17005 rqg-mdev17005
|
cd rqg-mdev17005
|
perl ./runall-new.pl --basedir=/data/bld/10.2-asan --vardir=/dev/shm/vardir --duration=350 --threads=4 --grammar=mdev17005.yy --skip-gendata --gendata-advanced --vcols
|
Notes:
- Don't forget to change the basedir value.
- The grammar is quite big and could definitely use some automatic simplification, but I'm not sure it's necessary, possibly the problem will be obvious right away.
- Reproducible on 10.2 and 10.3. On 10.0 and 10.1 I hit MDEV-17004 instead.
- The test reproduces the problem for me almost every time, but sometimes it misses the mark. Just run it again. You can also use this command line to run the same test a desired number of times:
perl ./runall-trials.pl --trials=10 --basedir=/data/bld/10.2-asan --vardir=/dev/shm/vardir --duration=350 --threads=4 --grammar=mdev17005.yy --skip-gendata --gendata-advanced --vcolsrunall-new.pl is replaced by runall-trials.pl --trials=N, all other options are the same. It will stop when the test fails for the first time.
