            Bug ID: 31897
           Summary: [gdb/symtab] FAIL: gdb.base/fission-macro.exp:
                    dwarf_version=5: dwarf_bits=32: strict_dwarf=0: info
                    macro FIRST
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

Here ( https://linaro.atlassian.net/browse/GNU-1258 ) the following FAIL is
reported on arm-linux:
...
(gdb) info macro FIRST
Defined at
/home/tcwg-buildslave/workspace/tcwg_gnu_2/abe/snapshots/gdb.git~master/gdb/testsuite/gdb.base/fission-macro.c:0
-DFIRST=1
(gdb) FAIL: gdb.base/fission-macro.exp: dwarf_version=5: dwarf_bits=32:
strict_dwarf=0: info macro FIRST
...

In contrast, on x86_64-linux I see:
...
(gdb) info macro FIRST^M
Defined at /data/vries/gdb/src/gdb/testsuite/gdb.base/fission-macro.c:18^M
#define FIRST 1^M
(gdb) PASS: gdb.base/fission-macro.exp: dwarf_version=5: dwarf_bits=32:
strict_dwarf=0: info macro FIRST
...

So, the line number for the macro definition seems to be incorrect: 0 instead
of 18, and consequently we get "-DFIRST=1" instead of "#define FIRST 1".
