I think you lost the battle to make the example readable but I've managed to put it back together enough to reproduce the problem, thanks. The problem occurs on the target instruction of a forward conditional assembly branch, and appears to suggest that the wrong ICTL setting is being used when lookahead processing is used in open code to skip ahead to find the target sequence symbol. Major changes to lookahead were implemented for APAR PI90075 in January 2018 (to make it compatible with AINSERT) so it's quite likely the problem was introduced there (in PTF UI53046 on z/OS). Although our HLASM regression testing suite has a large number of ICTL tests, it appears that it didn't pick up this bug. We suggest you report this as a defect in HLASM through the usual support channels. We have enough information to reproduce it so you only need a brief summary of the problem.
