Stability issues with 0.3-SNAPSHOT builds #69

Closed raz0red closed 4 years ago

raz0red commented 4 years ago

I have experienced several stability issues (crashes) with snapshot builds of the 0.3 release (main branch).

Crashes I have experienced occurred when:

I am currently working to track down what is causing these issues.

Please respond to this issue with any other stability problems that you experience when testing 0.3-SNAPSHOT builds.

Thanks!

These issues appear to always occur after running a CD-based game (PC-FX or PC-Engine).

I was also able to capture the stack trace on a recent crash. It doesn't tell a whole lot, but it is occurring during a heap free operation. Therefore, it appears that it may be a memory-related issue in the CD emulation portion of WiiMednafen. (That is just a guess, but definitely worth investigating)

Also, I wanted to mention that I set up a continuous integration (build) loop. For any commits made, there is a build available here:

https://github.com/raz0red/wii-mednafen/actions

If you click on an individual build, you will see the status of the build. If the build was successful you will see an "Artifacts" portion in the upper-right. If you download the artifact named "dist", you will find the distribution .zip file within it.

Tentatively closing based on fix in PR #70 (the stack size appears to have been exceeding and was overwriting the bluetooth-related code).

Refer to the latest builds for testing in the following location:

I just noticed that the "artifacts" tab is not available on GitHub unless you are logged in. However, if you look at the "Commit History" you will see a green check mark or red x depending on whether the build passed or failed. If you click on the check mark or x, it will allow you to click on "details", which will take you to the automated build. From there, you can download the artifact in the upper right corner (if it was a passing build).

raz0red commented 3 years ago

Just kicked off a new build. Please let me know if that works for you.
