Bug description:
The following script shows the SystemError:
classname_1[name_4]:classname_4[name_2](name_4):name_4
output (Python 3.12.0rc2+):
SystemError:compiler_lookup_arg(name='name_4')withreftype=3failedin<genericparametersofname_4>;freevarsofcodename_4: ('.type_params','name_4')
minimizing it further leads some different crashes:
The propably most interresting one is this, which does not look special at all.
classname_1[name_3]:classname_4[name_2](name_5):pass
output (Python 3.12.0rc2+):

@JelleZijlstra I think this is another one for you. Feel free to create a second issue if you think that they are unrelated.
