Current Behavior

================== C compilation error (from tcc): ==============
cc: /tmp/v_1000/option2.01KDY7C9X6QWEZ0K1W6VJZZKGQ.tmp.c:563: error: ';' expected (got "IError")
=================================================================
Try passing `-g` when compiling, to see a .v file:line information, that correlates more with the C error.
(Alternatively, pass `-show-c-output`, to print the full C error message).
builder error:
==================
C error found. It should never happen, when compiling pure V code.
