@eckard_klotz:
I think i can reproduce your error. But i think what is actually happening (and i can not understand why it only happens now): The ask dialog of the personality is not working...
If i use the flag --personality="ask" i get the dialog, and i select your MinGW_9_2_0bit_TDM personality, but in compiler executable settings the global variables are not shown, for me my default config is loaded.
You can check this in the Code::Blocks log tab, the first line: "Loaded config file"
if i use the flag --personality="MinGW_9_2_0bit_TDM" everything works
can you confirm this?
[Edit:] i started a new forum thread for this problem:
