[macOS debug mode] pyrogenesis_dbg process freezes or is extremely slow when starting the game

[Langbart]

to reproduce

• build the macOS debug version
  • BuildInstructions#Buildthegame macOS debug

./build/workspaces/update-workspaces.sh -j5 && cd gcc && make config=debug -j5

• this will create another executable called pyrogenesis_dbg in the /binaries/system folder
• run pyrogenesis_dbg and try to initialize a game or watch a replay

  # Example: start a Mainland map from the command line
  pyrogenesis_dbg -conf=mod.enabledmods:"mod public" -autostart="random/mainland"
  

• the loading page is displayed, from here are two possibilities
• (A) the process hangs, as shown in red, and I quit the process manually

• (B) it does spawn into the game after roughly 5mins, but its painfully slow and definitely unplayable.
  • the performance I received in this mode is even worse then what I described in #6193 (Ref: #6193)

notes

• all tests were done with the default settings
• I never used pyrogenesis_dbg for play testing, so I can't even give a rough estimate how long this has been broken
• this ticket was created after investigating Ticket #6699
