There you go. D2, run build.debug.sh to build. Modify the script to add
options and the like. Built with `-gc` list _Dmain or break _Dmain
doesn't work, if you force a segfault (remove the comments from the
first few lines of ator.main and compile with -noboundscheck to cause
one) bt doesn't work, etc, etc.
Thanks! I've managed to work this down to a 2 line test case:
----
void function() myfunc;
void main(){}
----
Wow, good work...
Which errors with:
----
Die: DW_TAG_padding (abbrev = 0, offset = 0)
has children: FALSE
attributes:
Dwarf Error: Cannot find type of die [in module /tmp/test]
----
Compile with either dmd -gc test.d or dmd -g test.d. I'll spend some
more time with it now and see if I can figure out a cause so we can give
a more useful bug report, if not I'll open a bug as is. If anyone else
is getting different errors from gdb when using -gc, let me know and I
can narrow them down too.
If I compile it with dmd -gc test.d, start gdb (version "7.0.1-debian"),
and type "break _Dmain", I just get "Dwarf Error: Cannot find DIE at 0x0
referenced from DIE at 0x46 [in module /tmp/test]".
This is with dmd v1.055 without gdb patches (but some other custom
patches, though I think none should affect the debugging infos).
