WARNING: Lexing literal_block '...' as "ini" resulted in an error at token: '}' #2834
Description
I originally filed this at sphinx, but guess it better fits here. It might be related to the 2.19 release as it first popped up today.
Describe the bug
A part of our docs that didn't change since quite a while suddenly causes a warning from the ini lexer and thus sphinx terminates with rc 1 (which leads to termination of our CI pipeline).
data-structures.rst:971: WARNING: Lexing literal_block '...' as "ini" resulted in an error at token: '}'.
Details see there:
I didn't see anything problematic in that ini section, even the {} were nested correctly.
