The "var_base#12" form in IR is ambiguous and can lead to errors.

[vsmenon]

Currently, the start compiler uses appends "_base" or "_offset" to a variable in the IR to indicate how to interpret it. E.g.,

• x#8 resolves to *(FP+8)
• x_base#8 resolves to 8

This is ambiguous if the variable actually ends in "_base". E.g., the following code runs incorrectly in Start.

import 'stdio.dart';

void main() {
int int_base;

int_base = 10;
WriteLong(int_base);
WriteLine();
}
