Description

Bug type: Debugger

Describe the bug

  • OS and Version: Debian 10 Buster (chromebook)
  • VS Code Version: 1.59.0
  • C/C++ Extension Version: v1.5.1

To Reproduce
Please include a code sample and launch.json configuration.
Steps to reproduce the behavior:
Launch debugger on Debian 10 Buster (GNU gdb 8.2.1) and start stepping through files. A popup with this error will happen on every step:

Unable to open 'poll.c': Unable to read file '/build/glibc-vjB4T1/glibc-2.28/sysdeps/unix/sysv/linux/poll.c' (Error: Unable to resolve non-existing file '/build/glibc-vjB4T1/glibc-2.28/sysdeps/unix/sysv/linux/poll.c').

Research direction

Start by reproducing the failure with Debian 10, VS Code 1.59.0, the C/C++ extension v1.5.1, GNU gdb 8.2.1, and the reported launch.json configuration while stepping through files. Trace how the debugger handles the reported /build/glibc-vjB4T1/glibc-2.28/sysdeps/unix/sysv/linux/poll.c path; done means stepping no longer produces the popup and the source file resolves or opens correctly.
