Affected releases: 0.3 BETA, 0.4 BETA, 0.5 BETA
An interrupt occuring during the execution of a CALL instruction, forces bit 11 of the target address saved on the stack to 0. This corrupts target addresses that are located in Program Memory Bank 1.
Fixed in: int.vhd 1.5 New regression test: white_box/int_on_call Fix will be included in next release.
