High CPU and memory with GDB

Environment

• OS and version: Windows 11
• VS Code: 1.78.2
• C/C++ extension: 1.16.0 & 1.15.4
• OS and version of remote machine CENTOS 7.9.2009
• GDB / LLDB version: GNU gdb (GDB) Red Hat Enterprise Linux 10.2-6.el7

Bug Summary and Steps to Reproduce

Bug Summary:
Debug my executable, before it even breaks in main or loads any symbols it spins for minutes at 100% CPU while allocating a ton of memory. Stepping through is very slow also. Using gdb from the command line is very fast, however a suboptimal experience. I have tried it with the system gdb also. I see the same behavior

Comienza con la configuración launch.json y los registros del depurador que muestran solicitudes repetidas de symbol-list-lines; reproduce el lanzamiento y compara el comportamiento de VS Code con el de GDB desde la línea de comandos. Rastrea la ruta de carga de símbolos y ejecución paso a paso implicada por esas solicitudes. Se considera terminado cuando la depuración ya no pasa minutos usando el 100 % de la CPU ni asigna memoria excesiva antes de main, y la ejecución paso a paso responde con fluidez.
