dear Ultrix wizards, I'm trying to debug a large fortran program which core-dumps after a segmentation fault. When I start the debugger, dbx2.0, and before dbx outputs its prompt, I get about 100 warnings like warning: unexpected symbol <symbol-name> in field list (many if not all of these symbols are names of common blocks and statement functions) after that, the debugger dies with an internal error: dbx: internal error: unexpect sc in . symbol (.ub_cinp.1) got 16 This is on a DECstation 5000 running Ultrix V4.1 & f77 V2.0, but I obtain the same behaviour on a DS3100 running Ultrix V3.1 and f77 V2.0 It looks a bit like some tables in the debugger might be overflowing, but I cannot find any options to dbx that might let me increase any such tables Does anyone understand what is going on here? Or how one might work around it? I hate debugging large programs by inserting print statements everywhere! Many thanks in advance for any help! - Haimo email: haimo@vxaluw.cern.ch (preferred) haimo@cernvax.cern.ch
