another case... (bah). And the issue is:
Visiting PHI node: msgcnt_138 = PHI <msgcnt_7(40), msgcnt_172(35)>
Argument #0 (40 -> 36 executable)
msgcnt_7: [0, +INF(OVF)]
Argument #1 (35 -> 36 executable)
msgcnt_172: [-INF(OVF), 2147483645]
Meeting
[0, +INF(OVF)]
and
[-INF(OVF), 2147483645]
to
VARYING
Intersecting
