On Linux dmd outputs faulty debug info.
There are several bugs in the debug info on linux, one of them I've
fixed (for most cases ie. anything that requires phobos, I'm working
on the other cases ie. anything that needs funky libraries that use
a lot of complicated function pointers), and another one you've sent
me a massive test case for which I'm working down to a manageable
size for a bug report now (I'd have done it by now, your make file
doesn't play nicely with my multilib system though ;)). Other than
those 2 bugs I don't know what else is blocking debug info on
linux... I'm becoming quite familiar with DWARF/dmd's backend code
for DWARF through all this debugging, so if I can get these bugs
fixed I'd be happy to work on any others while I have time.
On Windows optlink crashes when building code in debug. Current
situation is a complete disaster.
OPTLINK still has problems, hopefully this situation will improve as
it gradually gets ported to C and eventually open sourced (or at
least we can hope that happens ;)). If not I guess we need to either
write a new linker, or a new backend for dmd so it can output COFF
and use another linker.
a new backend like gcc (of gdc) or even better llvm (ldc)?
for linux that was already done, and for D 1.0 it works well (I am
using linux x86_64).
and debugging normally works, even tango's stacktrace...
windows is indeed a different story (but I know some people use gdc).
Hopefully we can sort this situation out and get debug info for D on
a par with C/C++ :)
