happens with any p4-16 problem.

I cannot reproduce this problem; I have run successfully p4test with two -v flags using test programs from the testdata/p4_16_samples folder.

With two -v flags, I had the issue with a program that is using another architecture definition (not v1model).

With three -v flags, following error happens on

./p4test --p4v=16 ~/bf-p4c-compilers/p4-tests/p4_16/apply_if.p4 -v -v -v

Can you please supply a program that reproduces this problem? apply_if is not part of the testsuite. I have tried several of the tests and none has failed yet.

Han, can you still reproduce now that #852 has landed?

If this is fixed perhaps we can close it.
