--- Comment #3 from Dlang Bot <[email protected]> --- dlang/druntime pull request #3515 "merge stable" was merged into master: - 414316556aa95fa5b3b03a558479ecd4ccacb86e by Martin Kinkelin: Fix Issue 22081 - Utterly broken DWARF v5 support This has actually been tested to work with LDC, fixing the `assert(0)` and **numerous** terrible issues of #3189 after looking at the DWARF v5 spec (section 6.2.4). LLVM apparently puts all directory/file name strings into the new .debug_line_str section (DW_FORM_line_strp form code, one of various encoding options); reading the strings from there would require mmapping that section too, not just the .debug_line one. So at least with LLVM, *all* source file paths (of according DWARF v5 line-number programs) in the exception backtrace string currently show up as `<unknown dir>/<unknown file>`. - 56bfaaf03c9ff8ea3a1c9bcf41259c941cccef26 by Martin Kinkelin: Fix Issue 22081 - Utterly broken DWARF v5 support This has actually been tested to work with LDC, fixing the `assert(0)` and **numerous** terrible issues of #3189 after looking at the DWARF v5 spec (section 6.2.4).
