I found a small reproducer: ``` import jax import gc for i in range(1000): print(jax.jit(lambda x, y: x * y)(1,i)) jax.clear_backends() jax.clear_caches() gc.collect() ``` On my machine (208 cores) this...

It looks like `flatc -c -o horovod/common/wire horovod/common/wire/message.fbs` does indeed update that one file correctly. However there is also `horovod/tensorflow/custom_call_config_generated.h` requiring an update but autogenerating that is a bit harder....

Can you split off the MDAnalysis EC into an extra PR? It is also needed in e.g. #19398

Just for reference: These are the regexes I use: ``` # Lines marked with LCov or coverity exclusion comments '.*// LCOV_EXCL_LINE' '.*// coverity\[dead_error_line\]' # Lines containing only braces '\s*[{}]*\s*' #...

Thanks for you analysis > This would be a behaviour change for the `--pem-path` case, and it does seem relatively _subtle_. I worry that it won't be obvious that supplying...
