A few more details if it'll help. It appears that no symbol table is loaded at
all on Leopard, whether using the gdb supplied with XCode 2.5 (gdb-696) or
XCode 3.1 (gdb-962). On Tiger (gdb-696 only), the situation is a little better,
but not much. Using the gdb command "info sources" on a simple Tango "hello"
program lists the following (comiled with "dmd -g") on Tiger, which lists no D
source files at all:
/System/Library/Frameworks/System.framework/PrivateHeaders/i386/cpu_capabilities.h,
/System/Library/Frameworks/System.framework/PrivateHeaders/machine/cpu_capabilities.h,
<command line>, <built-in>, /SourceCache/Libsystem/Libsystem-88.3.10//,
CommPageSymbols.st, {standard input}


Now, the same file compiled with GDC shows the following sources, with both
gdb-696 and gdb-962 on Leopard, and gdb-696 on Tiger (although the order is
different):
/System/Library/Frameworks/System.framework/PrivateHeaders/i386/cpu_capabilities.h,
/System/Library/Frameworks/System.framework/PrivateHeaders/machine/cpu_capabilities.h,
<command line>, <built-in>, /SourceCache/Libsystem/Libsystem-88.3.10//,
CommPageSymbols.st, {standard input}, ../shared/rt/typeinfo/ti_C.d, critical.c,
arraycast.d, ../shared/rt/util/string.d, ../shared/rt/util/hash.d,
