Backtrace

BACKTRACE IF RELEVANT

[bmag]

First thing, there is a gtags layer. Try using it instead of installing helm-gtags as an additional package.

Second thing, I couldn't understand what the conflict is. What do you mean that the observed behaviour is "delete c-c++ layer in .spacemacs"? What is the meaning of "helm-gtags is disappear"? The bindings don't work? Spacemacs deletes the package?

EDIT: re-reading what I wrote, I apologize if I was too harsh
