I tried a bisect and can verify that commit f16c46c856afbd41b115a6a50306c0c002cdb333 is good (release_7.01h-750-gf16c46c) commit b664510ec4811491e4611791c24591153abdf5f3 is bad (release_7.01h-800-gb664510) but the sequence is not bisectable: when it tries the middle commit 2699f4e9bc7695432cf6aaf1dd48e182b10c2847 (release_7.01h-775-g2699f4e) it gets "Symbol's value as variable is void: result-type" and it's not clear to me how to proceed with the bisection at that point. I tried skipping a bit, but the results were mixed at best. So it looks to me as if something in those 50 commits broke it.
