Intermittent regression test failures (debug build)

[zwoop]

Seeing this on some VMs:

REGRESSION TEST SDK_API_HttpTxnTransform started
[SDK_API_HttpTxnTransform] TSTransformCreate : [TestCase1] <<PASS>> { ok }
[SDK_API_HttpTxnTransform] TSHttpTxnTransformRespGet : [TestCase] <<PASS>> { ok }
Fatal: ../../proxy/InkIOCoreAPI.cc:545: failed assertion `sdk_sanity_check_iocore_structure(bufp) == TS_SUCCESS`
   blah5
X-7:       blah7
X-9:         blah9

This is on master.

Closing this for now.
