  "message": "[gdb/symtab] Fix \"file index out of range\" complaint\n\nWith the test-case included in this commit, we run into this FAIL:\n...\n(gdb) p var^M\nDuring symbol reading: file index out of range^M\n$1 \u003d 0^M\n(gdb) FAIL: gdb.dwarf2/dw2-no-code-cu.exp: p var with no complaints\n...\n\nThis is a regression since commit 6d263fe46e0 (\"Avoid bad breakpoints with\n--gc-sections\"), which contains this change in read_file_scope:\n...\n-  handle_DW_AT_stmt_list (die, cu, fnd, lowpc);\n+  if (lowpc !\u003d highpc)\n+    handle_DW_AT_stmt_list (die, cu, fnd, lowpc);\n...\n\nThe change intends to avoid a problem with a check in\nlnp_state_machine::check_line_address, but also prevents the file and dir\ntables from being read, which causes the complaint.\n\nFix the FAIL by reducing the scope of the \"lowpc !\u003d highpc\" condition to the\ncall to dwarf_decode_lines in handle_DW_AT_stmt_list.\n\nTested on x86_64-linux.\n\nBug: https://sourceware.org/bugzilla/show_bug.cgi?id\u003d29561\n",
