Summary: pdflatex enters endless loop on malformed align-environment in nonstopmode
Category: Build process
Group: v1.40.1
Resolution: None
Initial Comment:
On compiling the attached minimal example containing a malformed "align" environment, pdftex seems to enter an endless loop (does not terminate and 100% CPU load) if invoked as
pdftex \nonstopmode \input{test.tex}
which is how rubber seems to invoke pdftex. If run without nonstopmode, compilation immediately stops at an error prompt (as expected).
I do not know if this is an error with the amsmath-package defining the align-environment, but as it looks a little similar to bug #909 ( http://sarovar.org/tracker/?func=detail&atid=493&aid=909&group_id=106 ) I hope that it does fit here. I do not have another LaTeX compiler to test with.
