Description: I have a set of several Impress files, heavy on math formulas/images, a little larger (~2M) than I normally use. The content was from a textbook publisher initially in Powerpoint format, converted to Impress (which isn't a problem in other cases for me). These files work fine in my current version of Libre Office (7.5.1.2), but they fail in Portable Libre Office (7.5.4). More specifically: - At full size, the files fail to load in Libre Office Portable. - If I split the files into about half-size sections, then they all load, but crash Libre Office Portable at some variable point into playing the slideshow. - If I split the files into about quarter-size components, then they all load and play through all of the content successfully. Steps to Reproduce: Case A 1. Load full-size file in Impress Portable. Case B 1. Load half-size file, play slideshow in Impress Portable. Case C 1. Load quarter-size file, play slideshow in Impress Portable. Actual Results: A: File fails to load. "Read Error. Format error discovered in the file in sub-document content.xml at position 398, 2811 (row, col)." B: Application crashes part way through slideshow. C: Slideshow runs successfully to end. Expected Results: Slideshow should load & run in each case. Reproducible: Always User Profile Reset: No Additional Info: Version: 7.6.0.3 (x86) / LibreOffice Community Build ID: 69edd8b8ebc41d00b4de3915dc82f8f0fc3b6265 CPU threads: 8; OS: Windows 10.0 Build 22621; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded
Created attachment 189533 [details] Full-sized file Full-sized file that Impress Portable cannot load.
Created attachment 189534 [details] Half-sized file First half of full file: this file loads but crashes Libre Office Portable part way through playing slideshow.
Created attachment 189535 [details] Quarter-sized file A A roughly one-quarter sized section of the initial file. This and other like-sized files collectively contain all of the original file's content, and all load & play through that content successfully.
Created attachment 189536 [details] Quarter-sized file B
Created attachment 189537 [details] Quarter-sized file C

Note that I initially observed this bug in Libre Office 7.5, and re-confirmed it after updating to 7.6 (in each case with matching version on the production PC and the Libre Office Portable image).
Thanks for the report, but a more appropriate place is here: https://portableapps.com/forums/support/libreoffice_portable
Requesting that this be reopened. The Portable Apps people are saying this is intrinsically a Libre Office bug -- specifically, that these larger math files crash the normal 32-bit Libre Office, in versions 7.6.1/7.6.2. Portable Apps only echoes the 32-bit version of Libre Office which has this problem (apparently, as I myself don't have the 32-bit version installed). See observation to that effect here: https://portableapps.com/node/69361
