Multiple crashes at GocryptfsVolume_native_1list_1dir+64

[machschnell]

I'm seeing a multiple crashes at

GocryptfsVolume_native_1list_1dir+64

(see below for a representative stack trace.)

I've got about 1,200 files. Sometimes the crash occurs when I open the volume. Other times it seems to happen when choosing a particular folder or when importing a folder. Often I have to force quit DroidFS to solve the problem. The issue seem to set in after importing server hundred files across maybe a dozen folders. Disabling "Map folders (Recursively map folders...)" may be a workaround given that I haven't seen a crash since changing that setting. But a crash is never a good thing.

I've seen similar crashes on multiple devices but some of these were running rather the old versions of Android. Now I'm seeing on an up to date Android.

This might actually be a gocryptfs issue. I'll try file an issue against that project too.

[hardcore-sushi]

Thanks for your bug report. I don't think it's a gocryptfs issue, but rather the same issue as #302, which has been fixed with 4aa211b. Could you test from the latest source?

[machschnell]

I'm not an Android developer so I don't know how to build a version from source. If I had an APK for the 4aa211b build I could certainly test that but I only see officially released APKs under the Releases section. Should I be looking elsewhere?

I agree that the #302 issue stack trace looks much the same.

Pixel 7a so arm64-v8a is the build I'd need.

[Android-PowerUser]

I received a DroidFS 2.2.0 debug apk from @hardcore-sushi a week ago. It probably contains other improvements since July. Maybe also those from 4aa211b. I would be interested to know if this is like a beta.
