| <title>Bug-279780</title> | |
| <!-- | |
| The commit 135cab6161b31a3e700108733c3837a3b21f7f05 (and bug report https://bugs.webkit.org/show_bug.cgi?id=279780) | |
| that we are investigating provides a crucial clue. | |
| The commit message highlights a problem with "case-insensitive disjunction" in regular | |
| expressions and mentions that "Certain ASCII characters can introduce Unicode characters | |
| (and vice versa) when we add all case variations in a case insensitive regex." | |
| This could lead to "incorrect behavior in performSetOpWithMatches, since | |
| we assume that the matches are in sorted order." | |
| With this example you will available to create out of memory error if the webkit version is affected by this bug. | |
