Hi,Building with Xcode 7, once in a while I get the following warnings from the dsymutil tool (a few dozens): "could not find referenced DIE" Followed be a segmentation fault. Adding the verbosity flag, I got detailed information about the DIEs that had the error, e.g.: =========== while processing /p4client/ProAudio/dev_main/ProAudio/XcodeBuildProducts/Debug/libWaveShell-Common.a(GraphicStream_Utils.o): warning: could not find referenced DIE in DIE: 0x0001415e: DW_TAG_imported_declaration [99] DW_AT_decl_file [DW_FORM_data1] ("/Applications/Xcode7.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/sys/_types/_time_t.h") DW_AT_decl_line [DW_FORM_data2] (20047) DW_AT_import [DW_FORM_ref4] (cu + 0x4c4f5254 => {0x4c4f5254}) ============ How do I go about understanding the error, what caused it and how to solve it? BTW, the lib size being built is around 350MB. Could there be a size issue causing this seg fault? While I'm here, where could I download the full source code of dsymutil? All I found was links to separate files (https://opensource.apple.com/source/clang/clang-700.0.72/src/tools/dsymutil/) Thanks, Gil Moses.
Hi Gil -- This is not really a question about DWARF. This looks like a bug in Clang. You would get more help with this by sending your question to the LLVM/Clang mailing list. -- Michael Eager ea...@eagerm.com 1960 Park Blvd., Palo Alto, CA 94306 _______________________________________________ Dwarf-Discuss mailing list Dwarf-Discuss@lists.dwarfstd.org http://lists.dwarfstd.org/listinfo.cgi/dwarf-discuss-dwarfstd.org
