Some new details, from 
https://github.com/company-mode/company-mode/discussions/1276:

When this happens (the user types a quote character and the tab 
character is inserted), there is a message in the echo area:

   Completion function pcomplete-completions-at-point uses a deprecated 
calling convention

I'm going to add Stefan to Cc in case maybe he had a quick fix in mind, 
since I saw him reply to a similar-ish bug report about pcomplete 
integration.
