Crash quitting sdrangel when the SID window is open #2119

Closed dforsi closed 1 month ago

dforsi commented 1 month ago

With the version 1836ae3a74f5b6c9e16c0627974be0883e762cd3 tagged v7.20.1 (ie without my modifications) if I close the SID window before closing sdrangel, then there is no crash.

Steps to reproduce the crash:

With the default compilation I get:

[...]
2024-05-19 23:07:48.310 (I) WebAPIServer::stop: stopped web API server at http://:8091
Segmentation fault (core dumped)

When compiling with ASAN I get this:

[...]

I can't reproduce this. What distribution and version of Linux are you using?

dforsi commented 1 month ago

I'm using Debian testing and compiling with clang version 16.0.6 (27) on x86_64-pc-linux-gnu.

Today I learnt that we can get the outermost frames of a stack trace using a negative count, so this is my backtrace, omitting most of the lines that look duplicated:

I'm using Debian testing and compiling with clang version 16.0.6 (27) on x86_64-pc-linux-gnu.

Ok, I'm using gcc.

From the stack trace, probably something to do with the video player.
