Of course should not crash. If it works on 2.18 this is a regression. Also the stable release of QGIS is 2.18, not 3.*.

Please test with QGIS 3.2.1

Nyall,

Help -> Check Version says I'm current, 3.3 is next step.

I checked the web download page, it opened with the "documentation error" message in the screenshot. Does it deserve its own bug report?
The newest version there is the 3.2.0-1 that I have.

I see a "final-3_2_1" on Github - is that what you're suggesting? It takes me a couple of hours (if I'm lucky) to download a full version out here. And I'd hate to risk replacing what I have which is mostly working... But I guess I could keep 3.2.0 available alongside that 3.2.1?

I just remembered this issue and realized I now have 3.2.1 - so I tried the SQL query again. I was in a different QGIS project, but I was able to load the original file into my current project and repeat the query. It seems to me 3.2.1 has crashed in exactly the same way.

"SQL error 19297.JPG" shows the query and the error report. No message ever fills in, and mousing over the error dialog gets a wait cursor.
"SQL error 19297 crash report.JPG" shows the rest of QGIS with the crash report and id.

After the crash report and "restart QGIS", at the end of the reload of my "Recent Projects" screen, it showed several errors at the top of the project list area. It often shows such messages for such a short time I can't read even the one line that is visible.

The test file for my SQL query was:
C:\Users\loren\Giant Files\HEC-RAS Dam Break\QGIS Projects\TestProject\Profiles100-50-25LinesOnly\Profiles100-50-25.shp

I'm not sure if these are leftover from the crash, but I've never seen such reports at this point in QGIS operation:

2018-08-12T10:54:14     INFO    QGIS Ready!

So I tried a different SQL query on PostGIS tables, that I know works in pgAdmin4. Crash ID: 26a6ac7056ec4001ffdb66d4cdd268098d2a2145. Plus it took about ten times as long as pgAdmin4 execution before it crashed.

The reload showed even more strange error messages:

One more thing... After the crashes and reload, a strange project has appeared, both in the initial display screen and in the Open Recent menu. There is no "Projects" folder in OSGeo4W64. Perhaps this is the source of the "Unable to load" messages? I used the right-click remove option and it is now gone from both places.

Please try on QGIS 3.4.1, if the issue is still valid change the affected version, thanks.
