I'm sending this again because the first time I only sent it to the list.

Hello Simon,
I was unfortunately wrong.
The following commit is responsible for this issue: https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commitdiff;h=57f0489f384193f7c962fb2a20c9e2e867f86039
Before that, with the same settings, everything works fine.
I'm using this adblock file: https://bitbucket.org/pedro311/freshtomato-arm/downloads/dnsmasq.adblock
and this (more or less) config file: https://bitbucket.org/pedro311/freshtomato-arm/downloads/dnsmasq.conf
Using these settings, query the following domains (in random order, multiple times):
adservice.google.com
google.com
consent.google.com
play.google.com
google.com/etc/
I can get dnsmasq to SIGSEGV.
BTW, I have a ready dnsmasq with gdb symbols - how do I run it to get some info?
-------------------------------------
[querying some domain that (page) contains a lot of google stuff in it, but it's better to do it manually]

Hello Simon,
Thanks for answering. I'm helping Pedro, FreshTomato main dev. I'm acting as messenger.
Here's what he have found so far:
```
I'm checking now which commit is responsible for this problem. It looks like this one:
https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=snapshot;h=7c1212e3d1b88359d2c28fa2fe42fee2fcc39732;sf=tgz <https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=snapshot;h=7c1212e3d1b88359d2c28fa2fe42fee2fcc39732;sf=tgz>
Everything after that causes these problems. Once I know for sure, I'll try posting the log here with --log-queries enabled and if that doesn't help, then with gdb.
The previous bug was easy to find: https://github.com/FreshTomato-Project/freshtomato-mips/issues/6 , but this one looks more complex.
```
Thank you!
Mat (HommeOursPorc)
