在数学导向的文档中，我使用glossaries将大多数文内数学符号链接到文档前面的词汇表中的含义。使用不同的下标/上标实际上不会改变它们的含义，因此我重复使用该条目（同时也防止词汇表列表变得太长）。不同的符号有不同的默认下标，因此我使用该字段user1来存储默认值，并使用了稍作修改的解决方案https://tex.stackexchange.com/a/229879/221009。
当我将一个\gls调用嵌套在另一个调用的可选参数中时\gls，出现以下编译错误xelatex：
! TeX capacity exceeded, sorry [semantic nest size=500].
<recently read> {
l.37 $\gls{A}$ and $\gls{A}[x, \gls{B}]

此编译错误是由此 MWE 生成的

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
Here is how much of TeX's memory you used:
14056 strings out of 479819
218295 string characters out of 5895846
668191 words of memory out of 5000000

No pages of output.
发生了什么事（我思考某些递归出错了？），以及如何修复它？
答案1
我没有追踪它在哪里循环，但一个简单的解决方法是预先评估嵌套的内容，

\sbox\zz{\gls{B}}
