OK, so I ran it with -d and now I'm waiting for SIGSEGV. What then?<br>

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

<br>
<br>
Thanks for answering. I'm helping Pedro, FreshTomato main dev.
I'm acting as messenger.
<br>
<br>
Here's what he have found so far:
<br>
<br>
```
<br>
I'm checking now which commit is responsible for this problem.
It looks like this one:
<br>
<a class="moz-txt-link-freetext" href="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</a>
<a class="moz-txt-link-rfc2396E" href="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></a>
<br>
<br>
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.
<br>
<br>
The previous bug was easy to find:
<a class="moz-txt-link-freetext" href="https://github.com/FreshTomato-Project/freshtomato-mips/issues/6">https://github.com/FreshTomato-Project/freshtomato-mips/issues/6</a>
, but this one looks more complex.
<br>
```
<br>
<br>
Thank you!
