[regression] [5.1.2] variable override #201
Description
This issue introduced with 5.1.2 (5.1.1 and below are fine)
Reproduction repo: https://github.com/pi0/babel-plugin-istanbul-bug (Use yarn test)
Reverting this change by #192 fixes problem.
Details
When using @babel/preset-env:
import path from 'path'
function test() {
const _path = 'test'
return path.relative(__dirname, _path)
}Transpiles into: (Correct)
var _path2 = _interopRequireDefault(require("path"));
function test() {
const _path = 'test';
return _path2.default.relative(__dirname, _path);
}Using babel-plugin-istanbul@5.1.2: (Bug)
var _path = _interopRequireDefault(require("path"));
function test() {
cov_1523mz691.f[0]++;
const _path = (cov_1523mz691.s[0]++, 'test');
cov_1523mz691.s[1]++;
return _path.default.relative(__dirname, _path);
}Using babel-plugin-istanbul@5.1.1 (Correct)
var _path2 = _interopRequireDefault(require("path"));
function test() {
cov_1523mz691.f[0]++;
const _path = (cov_1523mz691.s[0]++, 'test');
cov_1523mz691.s[1]++;
return _path2.default.relative(__dirname, _path);
