As an example, (tested with an empty .julia folder), after precompile some package  
`compile_incremental(:Makie)`  
and launch julia with the `-J /path/to/precompiled/sysimg` switch, loading other package can fail,  
e.g.

```julia-auto
using DifferentialEquations

while without the `-J ...` switch, the packages work fine, so it’s likely not an issue with Makie/DifferentialEquations. Any ideas how to troubleshoot, or is it more suitable to file as an issue to package compiler? The same steps used to work before, but after some updates seems to be no longer working. Thanks!
