Description: |
Following script
causes a crash wish following error messages: X Error of failed request: BadAlloc (insufficient resources for operation) Major opcode of failed request: 53 (X_CreatePixmap) Serial number of failed request: 102 Current serial number in output stream: 104 Any multiplier between 0x1000 and 0x1fff cause a crash. With multipliers >= 0x2000 only the number of zeros over 0x2000 is displayed. Multiplier between 0x3000 and 0x3fff crashes again. The width of "0" in the used font is 8 pixels. Seems there is an integer overflow. | |||

There are several (old) tickets in this repository showing various issues boiling down to dimensions exceeding what a short int can handle (+/-32767). Not all of them are pathological though. A non exhaustive list is [3307625fff], [2421792fff] and [770578fff]. In the latter ticket, a comment by dkf on 2004-02-16 says it all about the philosophy in those cases. chrstphrchvz added on 2020-04-23 17:43:20:
This crash still happens on 8.6.10, and will likely continue to do so. The crash occurs when I don't know whether Tk should clip dimensions to avoid crashes, or argue that these cases are too unusual to merit workarounds. Non-X11 windowing systems appear to lack limitations like this one, and X11 is simply no longer the windowing system of the future. fvogel added on 2016-04-08 17:10:37: Doesn't crash on Windows (Vista). |
