With a large .bib file (like the one provided in the testcase),
under zsh:
$ repeat 50; do bibtool -q -- 'preserve.key.case = On' -- 'select{@InProceedings}' all.bib >| out.bib; md5sum out.bib; done

One can see that 2 instances have been corrupted.
Or:
while { bibtool -q -- 'preserve.key.case = On' -- 'select{@InProceedings}' all.bib >| out.bib; [[ `md5sum out.bib` = 246089a0c05153f40fdfc3349882dd2b* ]] } do ; done
then look at the out.bib file with less, and search for the DEL
character (Ctrl-V Ctrl-?). Here I get 3 of them.
It seems that when the output is corrupted, it is always in the same way.
