>Environment:
Cywgin 1.3.10
GDB 5.2.1 with Insight frontend.
sparc-elf GCC 2.9.5.
Pentium III 850 Mhz PC with 256 MB of memory running Windows 2000 Service Pack 2.
>Description:
When I compile the attached dwarf.c file with "sparc-elf-gcc -c -gdwarf-2 dwarf.c" I get the attached dwarf.o file.  Then I launch sparc-elf-gdb.exe and it goes into assembly language mode.  I also see "main" in the listbox that lists all the functions in GDB.  However, I cannot switch to source mode.  If I click on the file/module listbox, I can select dwarf.c and GDB will show the source lines.  However, I cannot set any breakpoints in this mode.  I can set breakpoints if I click on "main" in the function listbox and switch to assembly mode.  This problem also happens if I compiler dwarf.c with -gdwarf instead of -gdwarf-2.  If I use -g1 instead, then GDB can automatically go into source mode after loading dwarf.o and I can set breakpoints without any problem.  I don't know much about DWARF, DWARF-2 or GDB and am wondering if this problem is due to the compiler (or linker) generating the wrong DWARF-2 information or if it is a problem of GDB/Insight.  Incidentally, I can launch GDB in text only mode (-nw) and then set breakpoint on a line number by entering the commands manually.

    What happened with this? Last I saw it appeared to be a problem with GDB (but this is unconfirmed). Let me know what's happening.
