Using v0.4.4, dmd used to consume just over 1 GB of memory compiling my project. With v0.4.5-beta.1, I can see dmd memory consumption rise to over 1.8 GB, after which dmd fails with a "Memory allocation failed" exception. Same result for dmd 2.089.0 as for dmd 2.090.1.

My parser is generated as a module, not at compile time.

This problem was likely introduced by #269.
