sqf::create_unit invoker_lock crash #207
Description
branch: master
self compiled dlls
inside custom plugin
tested on: profiling / performance
When creating multiple units in a tight loop, I've experience weird ass random crashes (access violation) in the invoker_lock.
this crashes the game :
auto group = intercept::sqf::create_group(intercept::sqf::west());
for (int i = 0; i < 10; i++) {
intercept::sqf::create_unit(group, "B_Soldier_GL_F", intercept::sqf::get_pos(intercept::sqf::player()));
}
while this does not :
auto group = intercept::sqf::create_group(intercept::sqf::west());
for (int i = 0; i < 10; i++) {
intercept::sqf::create_unit(group, "B_Soldier_GL_F", intercept::sqf::get_pos(intercept::sqf::player()), {}, 20.f);
}
(Both as custom sqf command called from ingame so no intercept::client::invoker_lock)
apparently if one tries to create multiple units too close to one another something fails hard.
