Zeek in debug mode with ZAM enabled: Assertion failed: (body->Tag() == STMT_ZAM)

[awelzel]

One nitpick that may not having anything to do with this: The ZAM test doesn't pass on my local Zeek in debug mode because of an assertion in ZAM:

$ ZEEKPERFSUPPORT=1 zeek -O ZAM -e 'event zeek_init() {}'
Assertion failed: (body->Tag() == STMT_ZAM), function Exec, file ZAM-EvalDefs.h, line 6106.
[1]    46189 abort      ZEEKPERFSUPPORT=1 zeek -O ZAM -e 'event zeek_init() {}'
