bt + console logs

On pc Debian x86-64 with master sources updated today + brand new profile, I got a crash when changing Locale Settings.

Steps to reproduce:
1) Launch LO
2) Menu Tools/Options
3) Language Settings/Languages
4) Change Locale Setting
5) Click OK
=> Crash
Comment 1 Julien Nabet 2016-05-20 21:48:44 UTC
I don't reproduce this with LO Debian package

I found that the commit which caused regression was:

this part specifically:

I got this after building master last weekend on Windows 7, but couldn't reproduce with one of the daily builds this week, so I thought it was gone. Apparently it isn't.

As it's a crash, and right before the beta, raising priority to critical.
Comment 3 Aron Budea 2016-05-20 22:01:16 UTC
Noel, could you take a look?
Comment 4 Julien Nabet 2016-05-20 22:11:24 UTC
gcc (Debian 5.3.1-19)

Noel: I don't know why modernize-loop-convert doesn't work in this specific case.
So for the moment, it seems to me that the only way to avoid the crash is to revert this specific part of the commit.
Any thoughts?
Comment 5 Julien Nabet 2016-05-20 22:13:38 UTC
Sorry Aron, I've overwriten the status when I've applied my changes.
I put it back to NEW/critical

I'll set this as fixed seeing as NoelGs comments suggests that

On pc Debian x86-64 with master sources updated today, I confirm I don't reproduce this.
Thank you Noel for the fix.
