libjxl 0.6.1 has an assertion failure in LowMemoryRenderPipeline::Init() in render_pipeline/low_memory_render_pipeline.cc.

Looks like this is the patch:

https://github.com/libjxl/libjxl/commit/aff17c4a57eb1e4d7ef00ea728d33cdb5b2ca9da

So I guess we need another prerelease snapshot. The reporter's crash log has this, which *seemingly* indicates bad instructions were being run somehow, though I don't understand how that's possible via an assertion:

[1]    888096 illegal hardware instruction  ./decode_oneshot /tmp/poc /dev/null /dev/null

Maintainer, please bump.
