Node.js v25: "Maximum call stack size exceeded" when using old Solidity compiler versions

When running solc-js tests on Node.js v25+, compilation of older Solidity compiler versions (e.g., v0.4.20) fails with a `RangeError: Maximum call stack size exceeded error`. The issue affects older Emscripten-compiled soljson.js binaries. Node.js v24 and earlier seems to work correctly.

Start with the solc-js tests that compile older Solidity versions, using Node.js v25+ and a known older soljson.js binary such as v0.4.20; compare the result with Node.js v24. Trace the RangeError through the older Emscripten-compiled binary and confirm that the affected versions compile successfully without the stack overflow.
