https://issues.dlang.org/show_bug.cgi?id=14225 --- Comment #10 from Martin Nowak c...@dawg.eu --- (In reply to Walter Bright from comment #9) What is the prospect of this being done in time for 2.067? I'm working on that, but dwarf.c is a mess. So far everything I tried had to touch too much code, likely resulting in a regression. I think the simplest solution is to throw out DW_AT_siblings, it's not that useful anyhow. --

https://issues.dlang.org/show_bug.cgi?id=14225 --- Comment #11 from Martin Nowak c...@dawg.eu --- OK, found it. For TYref we set the pointer byte_size to -1. Wondering why we're emitting TYref for arrays though. --

https://issues.dlang.org/show_bug.cgi?id=14225 --- Comment #9 from Walter Bright bugzi...@digitalmars.com --- (In reply to Martin Nowak from comment #8) Indeed, fixing the type repetition of debug infos for arrays fixes the issue. The code is pretty ugly and needs some refactoring before fixing the incorrect hashing, but that'd be my preferred fix as it get's rid of a lot of unnecessary debug info.

https://issues.dlang.org/show_bug.cgi?id=14225 --- Comment #7 from Martin Nowak c...@dawg.eu --- For yet unknown reason gdb reads an incorrect sizeof for the .length variable of the string. This only applies to the arrays in main not the ones passed to the dup functions. It also works in lldb. It would be more optimal if dmd cached and emitted only a single instance per array type. Will try to implement that and see if it helps before spending more hours debugging gdb. --
