Hi All
I am forced into retracting what I have said a few days ago:
"I have already email Walter about this issue and as he is slow as usual
in addressing Linux back-end issues [...]"
Mea culpa.
Walter was very responsive (just to spite me? :)) and after a few nights
of email exchanges and hacking that went well after 2AM, we found that:
1) the DW_AT_comp_dir piece of DWARF debug info, which gives the build
path of a translation unit was being output correctly by the DMD compiler;
2) however, because it was in the DW_FORM_strp (offset to a string)
form, rather than a plain DW_FORM_string, the linkers on some systems
took the liberty to mess with it (see
http://sourceware.org/ml/gdb/2002-04/msg00144.html:
"Some linkers (including the GNU linker) can remove duplicate strings
from an executable's .debug_str section, and adjust DW_FORM_strp
references to point to the remaining unique copies.")
3) The resolution was to use DW_FORM_string, and everything works
correctly now.
Also, we have agreed upon the debug formats for dynamic D arrays and
associative arrays.
I have implemented support for the former in ZeroBUGS, and it will go
out soon.
After I get the new builds out, I will start looking into debugger
support for associative arrays (although I cannot promise to deliver
anything in the very near future, due to expecting a new family addition
any minute now).
cheers,

That (the above) is one of the reasons I like D.

Sweet

Again

I assume that DMD 1.011 will generate said new debug stuff??
After I get the new builds out, I will start looking into debugger
support for associative arrays (although I cannot promise to deliver

congrats x2!

wow, people around here ate totally amazing they get support for new features
working before the new features are working!
Did Walter push out some private alpha versions of 1.011?

I don't think he'd have to. If the format of the debugging info DMD will
output is specified, the debugger can be made to parse it without
needing to have access to a compiler that actually outputs it...
