[Mingw-users] libbfd/addr2line issues

[Ilie H. <lup...@gm...>]

Hello.

I'm currently trying to generate the stack trace for a thread in another
process, which was compiled using MinGW. Everything goes well, here's part
of the output:
libkdecore.dll![unknown]()
[O:/kde/svn/trunk/KDE/kdelibs/kdecore/kernel/kcmdlineargs.cpp @ 1531]
crashtest.exe!do_crash()()
[O:/kde/svn/trunk/KDE/kdebase/runtime/drkonqi/tests/crashtest/crashtest.cpp
@ 43]
crashtest.exe!level4(int)()
[O:/kde/svn/trunk/KDE/kdebase/runtime/drkonqi/tests/crashtest/crashtest.cpp
@ 97]

What troubles me is that I can't get the function name inside the
libkdecore.dll shared library. I use libbfd to get the function/file/line
info, and it seems to work for 2 out of the 3. Then I said it's worth trying
addr2line to see what it shows. Here's what I did:
O:\kde\bin>addr2line -e libkdecore.dll -j .text -f
100000
??
O:/kde/svn/trunk/KDE/kdelibs/kdecore/sycoca/ksycoca.cpp:431

Function name is wrong, and I don't understand why. It works ok, I think,
because the file name and line is correct in my case, and I assume it's
right for addr2line too. Changing the debug format (DWARF, stabs) didn't
solve my problem.

Sorry if this is the wrong place to ask, but do you know what I can do? I
have binutils 2.20.

Thank you,
Ilie.
