Summary: [gdb] Invalid DWARF output for function pointers
Product: D
Version: 1.055
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD

The following program causes dmd to produce invalid DWARF output, rendering the
program impossible to debug with gdb:
----
void function() myfunc;
void main(){}
----
When compiled with either -g or -gc, causes this error in gdb when setting a
breakpoint (eg b _Dmain):
----
Die: DW_TAG_padding (abbrev = 0, offset = 0)
has children: FALSE
attributes:
Dwarf Error: Cannot find type of die [in module /tmp/test]
----
>From what I can gather, the DWARF output is correct (objdump --dwarf gives no
errors), but the padding before .debug_info is incorrect, causing gdb to be
unable to read it properly.
