{ This might be an environment-specific question, but let's concentrate
on what the language says about this issue. -mod }
My class name length is too long to be truncated, but my program can
run successfully.
What's the consequence if I disable the warning and ignore it.
e.g.
class_1<class2<class3, int, char* >, class2<class3, int, char* > ,
class2<class3, int, char* >, class2<class3, int, char* >,
.... ...
Larger than 10000 characters.

This is a QoI issue.
In Annex B, we have following explanation and guidance for length of
identifier:
[quote Annex B]
Because computers are finite, C + + implementations are inevitably
limited
in the size of the programs they can successfully process.
Every implementation shall document those limitations where known.
[...]
— Number of characters in an internal identifier or macro name [1
024].
— Number of characters in an external identifier [1 024].
[...]
[end quote]
