  "message": "Space-efficiently destroy chained CXFA_FMSimpleExpression instances\n\nDestroy CXFA_FMChainableExpression objects iteratively in linear time\nand constant space.\n\nCurrently, chainable CXFA_FMSimpleExpression objects are destroyed\nrecursively, allowing the stack to overflow if the chain is long\nenough. This change allows for efficient destruction without the need\nto lower the FM2JS parser depth limit.\n\nFixed: chromium:1052724\nChange-Id: I44753693910230d961c8d4ea9aeb7a6305f9d1e5\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/66990\nCommit-Queue: Daniel Hosseinian \u003cdhoss@chromium.org\u003e\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\n",
