=============================================================

It seems bad that these stacks are all unsymbolized, but I did notice that they are almost all hitting an assertion that appears to be in WebRender code:
  assertion failed: descriptor.width > 0 && descriptor.height > 0

Specifically, this assertion: https://searchfox.org/mozilla-central/rev/588d8120aa11738657da93e09a03378bcd1ba8ec/gfx/webrender/src/texture_cache.rs#695
These crashes are also from a number of different install times, so it seems less likely that it is just one user with a broken machine.
The modules tab is empty, which likely means that something is causing us to not be able to read the module list from the minidump. We hit a similar issue in bug 1400952.

I downloaded the dump from comment 0 and jeez, yeah:
2018-03-09 11:43:56: minidump.cc:2648: ERROR: MinidumpModuleList count 2969 exceeds maximum 2048
This actually looks very similar to the issue froydnj hit in bug 1400952. If I dump the /proc/self/maps stream from the minidump, it shows that there are 2293 entries containing /dev/shm.
