Just wonder whether this is a bug of GDB?

I'm trying the debug my project and would like to watch one of the member variables "m_iFrames" can not be watched !!!

The error messages are like:

DEBUG>>00000671-var-create - * "m_iFrames"
DEBUG>>00000671^error,msg="mi_cmd_var_create: unable to create variable object"

I'm just wondering whether this is a GDB bug? Or, I need to set up something before I'm able to watch those member variables?

BTW, the local variables are able to be watched.

Urgent !! Please do help.

Best Regards
