bug#58984: 29.0.50; M-x compile misinterprets libcheck error message format

[Mattias Engdegård]

Thanks for the report. Is this bug conditional on the patches you mentioned? 
(Not my field of expertise if so.)

Can the bug be reproduced from a simple text file that, when presented in 
compilation-mode, results in the incorrect behaviour?
If not, what about a simple script that emits the text piecemeal with the 
correct timing for the bug to occur and that can be run in M-x compile?

(Not really going to OCR your screenshots to extract the text myself!)
