Summary0002997: Tech Trees gadget causes Spring 86.0 to crash in special cases
Descriptionzwzsg's Tech tree gadget (Better_Ranged_Counted_Multi_Tech.lua) causes a crash of Spring 86.0 when a unit is created that has the definitions:

  customParams = {
    ProvideTech = "-Prerequisite",
    RequireTech = "0 Prerequisite", },

It does not happen in Spring 85.0.
TagsNo tags attached.

It is perfectly reproducable for The Cursed (1.18 #svn). Here is the infolog.txt for a "clean" game: no gadgets except unit_script.lua (loading lua animation scripts), game_spawn (spawning starting units) and the tech tree gadget and no widgets at all.

The bug is easy to avoid for me by changing some unit definitions. Thus it is no big deal for The Cursed, but still - there seems to be something...

where to get 1.18? i couldn't reproduce it, too...

"Error: Spring: Fatal Error std::bad_alloc" seems to be an out of memory which let me think, that there is some infinite recursion...

like function a calls function a, calls a, calls a, ...

i don't know what the tags "RequireTech" + "ProvideTech" means...

does it crash, when its PrerequisiteA and PrerequisiteB ?

The SVN is "private" - you would need to register at https://portal.projectlocker.com. Or you can reproduce the bug in any (?) other game. I can reproduce it in ZeroK by giving a Rocko the above mentioned prerequisites (and copy the gadget into the game). Same effect => crash.

From zwzsg's description about the custom defs:

// Two mutually exclusive unit, of which you can have only one at a time:
[UNITINFO]
    {
    Name=Russell Edwin Nash;
    Unitname=macleod;
    Description=There can be only one;
    [CustomParams]
    {
        RequireTech=0 Highlander;
        ProvideTech=-Highlander;
    }
    ...
}
[UNITINFO]
    {
    Name=Victor Kruger;
    Unitname=kurgan;
    Description=There can be only one;
    [CustomParams]
    {
        RequireTech=0 Highlander;
        ProvideTech=-Highlander;
    }
    ...
}

 Thanks, *now* it is reproducable for me.

Edit: not our problem but zwzsg's, there is an infinite loop inside SplitStringNameAndQuantity
