Maybe 73_HR_FIX #218601 can cause this.

 id #665964 may be helpful, I got stuck in an error loop and was nearly unable to get out.
Comment 6 Marian Mirilovic 2013-04-25 16:32:13 UTC
115 ERs in 3 months ... reproduced also in 7.3.1
looks like regression in recent Dev & ported together with some fix into reelase73 branch

1. Created new php web page
2. select all code (Ctrl + A)
3. pressed delete

4. exception window shows up
Comment 8 Marian Mirilovic 2013-05-03 11:11:09 UTC
Mila, any chance to fix it into 7.3.1 ?

Issue #225451 which is integrated in release73 resolves #218601.
Comment 10 Miloslav Metelka 2013-05-06 15:42:04 UTC
It's certainly a race condition since unfortunately I can reproduce none of the reproduction steps described in users' reports.
So far I've found only one document-lock violation (that might affect the lexer) across php and it's PhpTypedTextInterceptor.afterInsert() but that one is not triggered in case of just selecting all the text and pressing delete. So there must be some other problem. I'll try to add some more asserts across lexer's code together with describing as much context as possible in order to find the problem.
Comment 11 Vladimir Riha 2013-05-07 09:10:23 UTC
I'm sorry, I can't find a way to reproduce it
Comment 12 Marian Mirilovic 2013-05-14 08:30:51 UTC
any progress ? I know it's difficult to fix bugs those we can't reproduce, but this one is rising pretty often and I that's the reason we need to address it in 7.3.1 I guess.

Comment 14 Miloslav Metelka 2013-05-21 14:06:41 UTC
Unfortunately I'm still not able to reproduce the problem.
Yesterday I've fixed issue #227419 but it will likely not eliminate this problem.
I'm working on some extra multi-threading tests for the lexer hoping to find the problem.
Comment 15 Miloslav Metelka 2013-05-22 14:56:36 UTC
I'm going to simplify the locking mechanism of the lexer in terms of issue #230125 but it will be a large fix that would be too risky for 7.3.1.

For 7.3.1 I've made a temporary fix to Token.text() that, in case of IOOBE, it logs the exception and returns an empty string.
