Description

The combination of tex.xdy and glossaries.sty in [example] resulted in the automated creation of input for xindy. That input if written by a human would clearly show a fundamental misunderstanding how xindy works, says Joachim (xindy).

Suggestion:
\newglossaryentry{foo}{..} should append the gls name ("foo") to the xindy-sort-key in order to make it unique (even after application of merge-rules).

Evaluation

This isn't a bug. The glossaries documentation states that you must provide the sort key if the name contains commands. For example:

\newglossaryentry{gamma_k}{
type=symbolslist,
name={\ensuremath{\gamma_k}},
sort={gamma_k},
description={missing text gamma}
}
This is analogous to \index where you can't do \index{\ensuremath{\gamma_k}} but must do \index{gamma_k@\ensuremath{\gamma_k}}.

The suggestion, if implemented in glossaries, would break plenty of existing documents that rely on the sort key behaving as documented (for example, dual-entry glossaries that use a prefixing system for the label). The solution is to either add the sort key for each entry or provide a command that sets the sort key from the label. For example:

\newcommand*{\newsymbol}[2]{\newglossaryentry{#1}{sort=#1,type=symbolslist,#2}}

\newsymbol{gamma_k}{name={\ensuremath{\gamma_k}},
description={missing text gamma}}

Update 2020-03-01: note that the glossaries-extra package's symbols option provides \glsxtrnewsymbol which does something very similar.
