Some further investigation shows that there might be another scenario --- readv() returned `-1` with a non-zero `errno`, but `errno` got changed to `0` in `return_cached_blocks()`. Another piece of debugging...

Thanks for the information, I'll give it a shoot later this week.

+1 to this issue, the handling of (non-foreign, i.e. without a `ForeignCcDepsInfo` provider) dependencies is no good here. My desired behavior is to symlink such dependencies each into its own...
To be clear, actually, all the outputs in `out_static_libs` can not be linked all together, because some of them define the same identifiers.
I've tried this way, but encountered some difficulties re: the include paths (i.e. the header files / dirs) in `CcInfo` associated with the foreign targets. For now, my workaround is...
