--------------------------------
Summary: [C++][Python] Segfault in test_exec_plan.py / test_joins
Key: ARROW-16417
URL: https://issues.apache.org/jira/browse/ARROW-16417
Project: Apache Arrow
Issue Type: Bug
Components: C++, Python
Affects Versions: 8.0.0
Reporter: David Li
Occurs during wheel verification. It also happens to master. The failure is
sporadic but fairly reliable. test_joins is parameterized; it's not consistent
in the parameters it occurs on, but it consistently occurs on that test.
The backtrace reaches into malloc_consolidate. MALLOC_CHECK doesn't help.
However:
{noformat}
(gdb) b main
Breakpoint 1 at 0x11ea20: file
/home/conda/feedstock_root/build_artifacts/python-split_1625973859697/work/Programs/python.c,
line 15.
(gdb) command 1
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".
>call mcheck(0)
>continue
>end {noformat}
This fairly consistently fails with "memory clobbered before allocated block"
but the location varies.
This may be a red herring though. I also tried LD_PRELOADING a secure build of
mimalloc to see if it would catch any sort of heap corruption but instead the
tests pass consistently with mimalloc.
