Description Arnaud Versini 2017-03-06 19:45:20 UTC
Description:
Every single conditional formatting uses a table of 8192 pointers during import, for a maximum of tokens of 80192, even if there is only one token in the formula. It's 32KB for x86 and 64kb with x86_64 and could result really fast to a memory. All those tables are keeped with the maximum size during the import.

Steps to Reproduce:
1. Creates a document with a looot of conditional formatting
2. Save it and reopen it


Actual Results:  
crash on 32 bits platforms

Expected Results:
no crash and correct import


Reproducible: Always

User Profile Reset: No
