I had an e-book I converted to MS-Word, and was trying to compile as a PB. It kept crashing Logos. I finally narrowed it down to certain single paragraphs that contain a mix of references and page numbers. Here is one example that, in a Word doc by itself, will consistently crash when compiling to PB:
Genesis 1 259, 263, 413, 416 1–2 414 1:26–8 266, 416 1:28 263 2 266, 292, 415 2:4 378, 385 2:19–20a 266 3 251 5:1 378, 385 6 251 9:1 263 9:7 263 10:1 378 12 260 12:2f. 263 12:3 262 15 260 15:16 228 16:10 263 17 260 17:2 263 17:6 263 17:8 263 22 260, 273 22:16ff. 263 25:8 331 25:12 378 25:19 378 26:3f. 263 26:24 263 28:3 263 34 220 35:11f. 263 41:14–28 255 41:45 220 47:27 263 48:3f. 263 49:9 315 Exodus 1:7 263 2:23–5 386 2:24f. 261 6:2–8 386 6:12 301 6:30 301 12:43 232 14:19f. 229 19 263 32:13 263 Leviticus 18:24–8 228 23:42 229 26:9 263 26:41 301 Numbers 15:30f. 275 24:17 166 24:17–19 313 32:22 263 Deuteronomy 1:10f. 263 4:25–40 261 6:4 248, 362 6:20–4 218 7:7f. 337 7:13f. 263 8:1 263 9:4–5 228 10:16 301 18:12 228 25:7–9 229 26:15 261 26:17–19 261 27–30 261, 387 27–32 271 27:15–26 387 28:1–2 387 28:3–6 387 28:5–9 218 28:7–14 387 28:15–68 261 28:16–19 387 28:20–68 387 28:63 263 29 387 29:6 301 29:16–28 261 30 387, 389, 406 30:1–10 261 30:5 263 30:6 301 30:14 388 30:15–20 388 30:16 263 31–4 261, 388 31:3–6 389 31:16–21 261 31:27 261 31:29 261 Joshua 24:2–13 218 Judges 5:5–21 218 Ruth 4:1–12 229 1 Samuel 1:1–2:11 379 5:1–5 473 16:13 379 17 380 17:26 473 17:36 473 17:43 473 17:45–6 473 18:6–16 999
If I drop the last 999, it compiles fine. Put the 999 back in, it crashes. If I put a paragraph break somewhere in the list, it compiles fine. There are a couple other similar paragraphs (mix of verse references and page numbers) that also cause a crash. . . this is the only one I narrowed down to "add or remove this single number to see the behavior."
This is using Logos 5.1b SR-3 on OS X.
