line 82 is a "return FALSE;" of trigger_activate_at_intersection() banked function.

[Philipp Klaus Krause]

Looks like the recent calling convention switch introduced a bug in the handling of banked functions.

[Philipp Klaus Krause]

Is there a chance to get a smaller reproducing example? Preferably just one function definition, and no dependencies on headers (other than the standard library that comes with SDCC)?

[Tony Pavlov]

i'll try to, Philipp

[Philipp Klaus Krause]

Can't check if this still affects current SDCC, since we do not have a self-contained code sample to reproduce the issue.

[Tony Pavlov]

it does not, it is ok to close this issue.
