#2410 bibtex buffer size exceeded

[U_Fischer]

Imho this is more a pgfplots bug, but as it works with texlive and with bibtex8 I'm reporting it anyway.

In the following document pgfplots writes a very long line to the aux-file (26.825 chars) and when one calls bibtex (miktex 32bit + 64bit) on this aux-file it fails:

G:\Z-Test>bibtex test-utf8
This is BibTeX, Version 0.99d (MiKTeX 2.9)
The top-level auxiliary file: test-utf8.aux
Buffer size exceeded!

The buffer size has been increased.
