DMD on Linux?

[Cristian Vlasceanu]

After more research, it appears that the bug that I am seeing is not the 
DMD compiler's fault:

dmd -g -c nested.d
readelf -w nested.o
produces:
[snip]
<0><b>: Abbrev Number: 1 (DW_TAG_compile_unit)
      DW_AT_stmt_list   : 0
      DW_AT_name        : nested.d
      DW_AT_comp_dir    : (indirect string, offset: 0x0): 
/home/cristiv/workspace/d
      DW_AT_producer    : Digital Mars D v1.010
[/snip]

So far we're okay! DW_AT_comp_dir is correct

dmd nested.o
(invokes) gcc nested.o -o nested -m32 -lphobos -lpthread -lm

readelf -w nested
produces:
[snip]
<0><121>: Abbrev Number: 1 (DW_TAG_compile_unit)
      DW_AT_stmt_list   : 0xc7
      DW_AT_name        : nested.d
      DW_AT_comp_dir    : (indirect string, offset: 0x0): short int
      DW_AT_producer    : Digital Mars D v1.010
      DW_AT_language    : 19     (Unknown: 13)
[/snip]

Directory is "short int"??? Obviously the linker screwed it up.
