I can pseudo-deterministically reproduce this DCHECK by launching chrome on android, using Linux chrome://inspect/?tracing to take a memory-infra dump. Then killing Chrome, and repeating this process.

Build settings:
"""
  3 target_os = "android"                                                           
  4 use_goma = true                                                                 
  5 is_debug = false                                                                
  6 is_component_build = false                                                      
  7 symbol_level = 1
