Thanks for bash in the first place. > Fixed in the next version. Chet, is there any workaround for existing versions? I mean, there must be some memory corruption involved in here, so is it possible to dodge it without upgrading? For instance, would simply avoiding the "-t" option of "read" be enough to guarantee no memory corruption? Other? Thanks a lot in advance! I know: the answer to this question is probably in the latest revision of the source code, but... I doubt I will fully understand what is happening there. And I am surely not the only one in this case. Cheers, Marc
