--------------------------------
Summary: [C++][CI] Enable libSegFault for C++ tests
Key: ARROW-17093
URL: https://issues.apache.org/jira/browse/ARROW-17093
Project: Apache Arrow
Issue Type: Improvement
Components: C++, Continuous Integration
Reporter: David Li
Adding libSegFault.so could make it easier to diagnose CI failures. It will
print a backtrace on segfault.
{noformat}
env SEGFAULT_SIGNALS=all \
LD_PRELOAD=/lib/x86_64-linux-gnu/libSegFault.so
{noformat}
This will give a backtrace like this on segfault:

Caveats:
* The path is OS-specific
* We could integrate it into the build tooling instead of doing it via env var
* Are there easily accessible equivalents for MacOS and Windows we could use?
