The problem is there is not debug symbols packaged as a biarch package in Debian, meaning that valgrind is mostly useless used with libc6-i386. In other words there is no libc6-i386-dbg package as you note later: > For 64-bit binaries (shown above) /lib/x86_64-linux-gnu/ld-2.13.so > (installed by libc6) does have a .gnu_debuglink section pointing to > the debug-version of located in /usr/lib/debug (more specifically > /usr/lib/debug/lib/x86_64-linux-gnu/ld-2.13.so) which is installed by > libc6-dbg. To behave properly, you have two roads, either ask the libc maintainer to provide a libc6-i386-dbg package, which between us, wouldn't really be the proper way, or more simply, use multiarch. For that: # dpkg --add-architecture i386 # apt-get update # apt-get install libc6-i686:i386 libc6-dbg:i386 For *some* reason I don't really understand, the first time I ran your testing-32 I had to specify the full path to the ld.so in this fashion: $ valgrind /lib/i386-linux-gnu/ld-2.13.so ./testing-32 But it's now fine and runs properly when I just do: $ valgrind ./testing-32 I've no real clue on *why* it didn't work the first time, probably some kind of ld.so.cache or something. I've put the glibc maintainer in the loop because it's not clear to me why "valgrind ./testing-32" failed in the first instance, maybe he'll have a clue, I suspect that "ldconfig" didn't do the right thing because of the fact that I have three libc's: libc6:amd64, libc6-i686:i386 and libc6-i386:amd64… and it probably picked the wrong ones.
