http://d.puremagic.com/issues/show_bug.cgi?id=2604 Summary: DW_TAG_module and GDB Product: D Version: 1.029 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: bugzilla digitalmars.com ReportedBy: mihail.zenkov gmail.com I try fix GDB to support DMD 1.029 and greater. DMD set flag "has children" to DW_TAG_module and in this case GDB can't find DW_TAG_subprogram, as result we don't have psymbols. If i change flag to "no children" GDB load psymbols without problems. Is it bug DMD or GDB? Why DMD set this flag? --

http://d.puremagic.com/issues/show_bug.cgi?id=2604For those of us waiting for this bug to get fixed, is there any relatively easy thing we can do to get gdb to work?1. Use GDC or DMD-1.028. Currently DMD specific DWARF extensions not supported. http://www.digitalmars.com/d/1.0/abi.html 2. Try patch binary before debug it. For example we have binary crash_test. With next command we can see if DW_TAG_module have "has children" flag: objdump -W crash_test 2>/dev/null | grep DW_TAG_module <1><138>: Abbrev Number: 2 (DW_TAG_module) 2 DW_TAG_module [has children] Try patch it: sed "s/\x1e\x01\x03\x08/\x1e\x00\x03\x08/" -i crash_test And see again what we have: objdump -W crash_test 2>/dev/null | grep DW_TAG_module <1><138>: Abbrev Number: 2 (DW_TAG_module) 2 DW_TAG_module [no children] --

http://d.puremagic.com/issues/show_bug.cgi?id=2604 I had hoped this would be a workaround for http://d.puremagic.com/issues/show_bug.cgi?id=2575 but alas, it does not :( For others trying the sed command, I think you need to use greedy replacement. (add a g between the last / and "). Without that, it did not fix all occurances of has children for me. --
