  "message": "Avoid N^2 copies in CXFA_FMDotAccessorExpression::ToJavaScript().\n\nThe local tempExp1 will be repeatedly copied into its caller\u0027s\ntempExp1 getting larger each time as the recursion unwinds. The\ncost now is we may have to generate a string twice, but we do\nso into a single buffer.\n\nThe referenced bug seems recurse until we hit the 5000 frame\nlimit in the depth manager.\n\nWe\u0027ll probably need a follow-up bug to look at the other temporaries.\n\nBug: chromium:1274018\nChange-Id: Ieafcc1e3e1aab412cbcb447f5bcb87d43ab364a2\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/87732\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Tom Sepez \u003ctsepez@chromium.org\u003e\n",
