I had to rewrite this to use evalInFrame() in order to bisect it: { let x00, x01, x02, x03, x04, x05, x06, x07, x08, x09, x0a, x0b, x0c, x0d, x0e, x0f, x10, x11, x12, x13, x14, x15, x16, x17, x18, x19, x1a, x1b, x1c, x1d, x1e, x1f, x20, x21, x22, x23, x24, x25, x26, x27, x28, x29, x2a, x2b, x2c, x2d, x2e, x2f, x30, x31, x32, x33, x34, x35, x36, x37, x38, x39, x3a, x3b, x3c, x3d, x3e, x3f, x40, x41, x42, x43, x44, x45, x46, x47, x48, x49, x4a, x4b, x4c, x4d, x4e, x4f, x50, x51, x52, x53, x54, x55, x56, x57, x58, x59, x5a, x5b, x5c, x5d, x5e, x5f, x60, x61, x62, x63, x64, x65, x66, x67, x68, x69, x6a, x6b, x6c, x6d, x6e, x6f, x70, x71, x72, x73, x74, x75, x76, x77, x78, x79, x7a, x7b, x7c, x7d, x7e, x7f, x80, x81, x82, x83, x84, x85, x86, x87, x88, x89, x8a, x8b, x8c, x8d, x8e, x8f, x90, x91, x92, x93, x94, x95, x96, x97, x98, x99, x9a, x9b, x9c, x9d, x9e, x9f, xa0, xa1, xa2, xa3, xa4, xa5, xa6, xa7, xa8, xa9, xaa, xab, xac, xad, xae, xaf, xb0, xb1, xb2, xb3, xb4, xb5, xb6, xb7, xb8, xb9, xba, xbb, xbc, xbd, xbe, xbf, xc0, xc1, xc2, xc3, xc4, xc5, xc6, xc7, xc8, xc9, xca, xcb, xcc, xcd, xce, xcf, xd0, xd1, xd2, xd3, xd4, xd5, xd6, xd7, xd8, xd9, xda, xdb, xdc, xdd, xde, xdf, xe0, xe1, xe2, xe3, xe4, xe5, xe6, xe7, xe8, xe9, xea, xeb, xec, xed, xee, xef, xf0, xf1, xf2, xf3, xf4, xf5, xf6, xf7, xf8, xf9, xfa, xfb, xfc, xfd, xfe, xff; evalInFrame(1, ""); } The first bad revision is: changeset: 64296:67b102d581dd user: Jim Blandy <jimb@mozilla.com> date: Tue Mar 15 12:18:36 2011 -0700 summary: Bug 554955: Give blocks and call objects unique shapes when they have parents that may be extended with new bindings. r=jorendorff
Created attachment 570757 [details] [diff] [review] v1 This pokes a hole in the Shape abstraction. I am guessing the eventual answer is to use Bindings for let-bindings too, not just var-bindings. Then PopStatement could just call tc->bindings.makeImmutable(). I'm not sure how much work that will be, so I'm spot-fixing the bug. Regression tests pass.
