Actual Behaviour
Error:
at Array.push (<anonymous>)
at LogicalExpression.getLiteralValueAtPath (file:///private/tmp/s2/node_modules/vite/node_modules/rollup/dist/es/shared/node-entry.js:13090:53)
at IfStatement.getTestValue (file:///private/tmp/s2/node_modules/vite/node_modules/rollup/dist/es/shared/node-entry.js:12054:77)
at IfStatement.include (file:///private/tmp/s2/node_modules/vite/node_modules/rollup/dist/es/shared/node-entry.js:11991:36)
This is due to:
this.expressionsToBeDeoptimized.push(origin);
note that this.expressionsToBeDeoptimized.push is set like:
this.expressionsToBeDeoptimized = EMPTY_ARRAY;
and EMPTY_ARRAY has Object.freeze(), so it's not mutable.
This started happening only in 4.29
