Possible bug

Is this a possible bug in a feature of sharp, unrelated to installation?

• Running npm install sharp completes without error.
• Running node -e "require('sharp')" completes without error.

If you cannot confirm both of these, please open an installation issue instead.

Are you using the latest version of sharp?

• I am using the latest version of sharp as reported by npm view sharp dist-tags.latest.

If you cannot confirm this, please upgrade to the latest version and try again before opening an issue.

If you are using another package which depends on a version of sharp that is not the latest, please open an issue against that package instead.

What is the output of running npx envinfo --binaries --system --npmPackages=sharp --npmGlobalPackages=sharp?

What are the steps to reproduce?

Convert animated .gif to animated .webp. Save and load into sharp again, then run .extract

What is the expected behaviour?

No segmentation fault

Please provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem

await sharp('test.gif', {
animated: true,
}).extract({left: 0, top: 0, width: 50, height: 50}).toBuffer(); // no segfault

await sharp('test.gif', {
animated: true,
}).webp().extract({left: 0, top: 0, width: 50, height: 50}).webp().toBuffer(); // no segfault

const buffer = await sharp('test.gif', {
animated: true,
}).webp().toBuffer();

await sharp(buffer, {animated: true}).extract({left: 0, top: 0, width: 50, height: 50}).toBuffer(); // segfault
