# Biber stops with no warning [closed]

After update, biber (version 2.1 now) stopped without giving anything after the "INFO - Decoding LaTeX character macros into UTF-8". The same file was compiling before.

System is Ubuntu 15.10.

• After splitting my bib file, I discovered this behaviour was caused by the entry (this is copy-paste from Zentralblatt output) Abstract = {{Der Verf. ... \aligned \format \r \quad &amp;\r\ (x&gt;0) &amp;(1\leqq u\leqq U) \endaligned}}, The culprit is the "\r " which you can just change to "\r\ ". This sounds like an unwanted behaviour (the content should not be processed). This message is for the record, maybe to get reasons why, but also to help others in a similar mess :) HTH! I'm happy to be in the clear :) Best, A., Olivier – Olivier May 9 '16 at 11:27
• I'm voting to close this question as off-topic because the issue is caused by a malformed entry in the bib file – egreg May 9 '16 at 12:03

Abstract = {{Der Verf. ... \aligned \format \r \quad &amp;\r\ (x&gt;0) &amp;(1\leqq u\leqq U) \endaligned}},

The culprit is the \r which you can just change to \r\. This sounds like an unwanted behaviour (the content should not be processed). This message is for the record, maybe to get reasons why, but also to help others in a similar mess :)
