Thanks for the report. I fixed this in a different way in the devel branch; the fix will be in the next bash release.

The tag table for bash.info included in bash-5.1.tar.gz is incorrect.

For example:

"Node: What is Bash?^?3029"

(in line 11988 of bash.info)

Means this node starts at byte address 3029, but in fact it starts at byte address 3020.

Recreating bash.info with the provided makefile doesn't fix the issue.

It seems this is due to the way bash.info is created. First bashref.info is compiled from the documentation, and this is later piped through

    sed -e 's|bashref.info|bash.info|g'

to create `bash.info`. That modifies byte addresses, rendering the tag table incorrect.

A quick workaround would be changing the sed pipe to e.g.

    sed -e 's|bashref.info,|bash.info,   |g

which seems to work ok and keeps the byte addresses unchanged.

I noticed the issue while using pinfo (https://github.com/baszoetekouw/pinfo) which complains with "Tag table is corrupt, trying to fix... (press a key to continue)" when following a menu entry.
