Very Strange: Stack trace missing the real line error and prints other line

[busslina]

Hi, I have seen this error several times and this is the first time I report it.

Basically in some situations, a runtime error gets badly printed, as it points to near line but not the correct one:

I did a video showing it. It might be a little bit confusing as it uses rearch concept and might not be very popular, but as I had this issue in the past I can assure is not rearchrelated.

In few words, the real error is being triggered by app.capsules.dart line 34 (_defaultAppVersionCapsule) but the reported error says app.capsules.dart line 16 (_defaultAppNameCapsule).

So... digging more I tried with a different error string and it seems to correct it. Then using again the same string the error came again.

(Sorry about the noise...)

The first image will point at line 16 (bad).
The second one will point at line 36 (good).

Looks like a compiler that tries to compile two equivalent function bodies into the same code, but messes up the line numbering.

//cc @derekxu16 can you check if this an issue with CFE or with the JIT compiler.
