            <title>[CDRIVER-2538] Benchmark build occasionally segfaults</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-2538</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;The following benchmark builds ended with segfaults:&lt;br/&gt;
&lt;a href=&quot;https://evergreen.mongodb.com/task/mongo_c_driver_perf_c_driver_benchmark_mongo32_BenchMarkTests_8744119d0293908358f3aec5e95b5534ca0c47c0_18_03_06_17_05_21&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://evergreen.mongodb.com/task/mongo_c_driver_perf_c_driver_benchmark_mongo32_BenchMarkTests_8744119d0293908358f3aec5e95b5534ca0c47c0_18_03_06_17_05_21&lt;/a&gt;&lt;br/&gt;
&lt;a href=&quot;https://evergreen.mongodb.com/task/mongo_c_driver_perf_c_driver_benchmark_mongo32_BenchMarkTests_30085af2124de68fd5ad714309f3ea2688489dee_18_03_02_02_42_22&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://evergreen.mongodb.com/task/mongo_c_driver_perf_c_driver_benchmark_mongo32_BenchMarkTests_30085af2124de68fd5ad714309f3ea2688489dee_18_03_02_02_42_22&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Unfortunately they aren&apos;t consistently breaking, and I didn&apos;t have any luck reproducing them.&lt;/p&gt;

&lt;p&gt;Let&apos;s add a debug build side-by-side with backtracing enabled so the next time it fails we can get more info.&lt;/p&gt;</description>

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;revert the the changes above and remove the debug benchmark&lt;/li&gt;
	&lt;li&gt;check if a stack trace on the release will at least give us function names. If so, then enable it.&lt;/li&gt;
	&lt;li&gt;possibly have the task upload the core dump&lt;/li&gt;
	&lt;li&gt;locally build and test with ASAN/UBSAN to see if that gives any helpful info&lt;/li&gt;
