------- Comment #4 from burnus at gcc dot gnu dot org 2007-10-19 21:16 ------- I'm not completely sure which bug is triggered that, but the error occurs for the expression character(len(str)) :: UpperCase
"str" is a dummy (of the interface function UpperCase) and despite being a dummy it is not a dummy of the current entry function (which is "ExportZMX"). The check assumes: Dummy + not-dummy of current function => Dummy of another Entry -> invalid. The solution is to add a check whether the dummy in in the current name space or not. I could not find any bit in the patches which caused this, but my un-educated guess would be http://gcc.gnu.org/viewcvs?view=rev&revision=127939 which added some character substring fixes.
