Stack imbalance (PROTECT error)

[jeroen]

I noticed that every output log of BiocCheck::BiocCheck("somepackage.tar.gz") ends with this:

Warning: stack imbalance in '<-', 18 then 20
Warning: stack imbalance in '{', 14 then 16

Which probably means there is an incorrect UNPROTECT() call somewhere in the a package used by BiocCheck itself.

For example (at the bottom)

• https://github.com/r-universe/bioc-release/actions/runs/19595221875/job/56119638854
• https://github.com/r-universe/bioc-release/actions/runs/19595221133/job/56119652652

Not sure how to debug this, maybe @kalibera has a tip.

I noticed the same issue.

It might be related to Bioconductor/graph#26.

graph is one of the few Bioconductor dependencies for BiocCheck that has compiled code.

Feel free to re-open if the issue persists. Thanks!

I'm still seeing the warnings in a workflow that uses graph 1.89.1 so there might be another source 🤔
