Calling an inline process inside another inline process causes the compiler to freeze

[BrainStone]

I've tried to reproduce it with a minimal example but didn't manage to get that working.

When trying to compile the following script the compiler always freezes.

String genericTags = "Marker:1b,NoGravity:1b,Invulnerable:1b,Invisible:1b"

install {
  /gamerule commandBlockOutput false
  /gamerule logAdminCommands false
  /gamerule doDaylightCycle false
  /gamerule doWeatherCycle false
  /gamerule keepInventory true
  /gamerule randomTickSpeed 0
  /gamerule announceAdvancements true
  /gamerule doFireTick false
  /gamerule doMobSpawning false
  /gamerule doMobLoot false
  /gamerule doEntityDrops false
  /gamerule spawnRadius 0

  /worldborder damage buffer 0
  /worldborder damage amount 100
  /worldborder warning time 0
  /worldborder warning distance 0
  /worldborder set 501
  
  /scoreboard objectives add BM_Variables dummy
  /scoreboard objectives add BM_Constants dummy
  
  start generate
}

uninstall {
  clean_up()
}

process clean_up {
  /kill @e[tag=BM]

  /scoreboard players tag @e[tag=Seeder] remove Seeder
  /scoreboard players tag @e[tag=Generator] remove Generator
}

impulse process generate {
  /summon armor_stand -9 21 -9 {${genericTags},Tags:["BM","Seeder"]}

  /scoreboard players tag @e[tag=Secondary] add Seeder
  /scoreboard players tag @e[tag=Secondary] remove Secondary
  
  create_seed()
}

process create_seed {
  //execute @e[tag=Generator] ~ ~ ~ /scoreboard players operation
}
