info hangs in string_in_line on malformed input file

[Nathaniel Beaver]

Steps to reproduce:

info -f ./bug.info.gz


Expected behavior:

info exits with an error such as "Cannot find node 'Top'".


Actual behavior:

info stuck in an infinite loop


Discussion:



File: example.info,  Node:^_

This appears to make info unable to find the node name.


Version:

info (GNU texinfo) 6.5



Sincerely,

Nathaniel Beaver

The malformed input file bug.info.gz has a section separator and newline after "Node:", like this: (also reproducible with 6.7dev, git commit d5666eb167a9edd20ed3cc86f49a6d40a4d94134).
