When command has a dot, it causes a syntax error

[Tatsh (Andrew Udvare)]

I have the bash port installed and I have it as my default shell. I have bash-completion sourced in my bashrc. Everytime I try to invoke a completion and the command has a period in it, I get a syntax error:

cargo2port.tcl <TAB>bash: cargo2port.tcl: syntax error: invalid arithmetic operator (error token is ".tcl")

I reported this to upstream but I am not sure if this is something they should handle or if it's something caused by my bashrc (although I've tried to narrow this down as much as possible).

I am wondering if it has anything to do with the Bash build as I do not get this error on my Gentoo machine and everything there is nearly identical in terms of the shell, rc, and version numbers.

Unfortunately I was not able to reproduce the problem on my system. I also modified my PATH to include this cargo2port.tcl file.

You could try to find the original line producing this message by enabling set -x in your shell, but be aware that this will produce a lot of debugging output from bash completion when pressing Tab.

I put together a clean VM and set up everything without my own rc files and it seems like it's a problem on my end.

I've tried debugging with -xv and it has not been very helpful. Upstream has the issue. This can be closed here.
