Is this a regression?

Yes and no. Version 8 and 9 without ivy work just fine. However ivy has problems with aot.

Description

After updating existing Angular project from version 8 to 9, compilation with ivy and aot leads to “ERROR in Maximum call stack size exceeded”. Non-ivy compilation works fine with or without aot with all optimization options. Also ivy WITHOUT aot works fine regardless of optimization options.

After much work I have isolated the problem to a module containing a highly mutually interdependent classes. More specifically if any class is imported from that module aot compilation crashes.

🔬 Minimal Reproduction

I have separated the troublesome module from the larger project and created a minimal test bench and can share it via github private repo on request.

@SPKorhonen - the problem is in your code. The Angular compiler is trying to statically analyse the code and it gets to this method:

static getBaseFreqMHz(p_Gamma: number, p_FieldStrength: number) {
  return SpinShift.getBaseFreqMHz(p_Gamma, p_FieldStrength);
}

which is infinitely recursive. And so the static analyzer is unable to stop - leading to a call stack overflow.

Thanks for very fast reply.

Unfortunately the nightly did not resolve the problem.

I have send invitations for the aot-crash repo.

FYI: the problematic module is aot-crash/src/app/spin/spinsystem.ts which is used within aot-crash/src/app/crash.service.ts
