I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment What is my problem with MeshFunction?
@MichaelE2. It is easier and more efficient to loosen the chop tolerance. Boole[Chop[Cos[#1], .01] == 0 && #2 > 0] & works fine of the domain {x, 0, N[15 Pi]} without increasing PlotPoints.

@MichaelE2. Do you think the multiplicity invalidates my answer?

comment Compiler stack overflow
Make your "huge function" smaller? Perhaps by breaking in to several sub-functions that can compiled separately.

comment When must I use the Return function?
I feel your answer is entirely complementary to mine, and is exactly the kind of additional answer I was hoping would be posted.

I gave a link to Rojo's answer in my answer as auxiliary reading. It's a great contribution and definitely related to this question, but in my opinion, not quite on-topic for the issue under consideration here.
