To view the full trace u can symlink
/compat/linux/lib -> /lib under 4.x -> 5.1
in 5.2+ is more complicated and u have to symlink the individual files
for the debugger to find them. an alternative may be to install
a linux version of gdb but not tried that:
The following may be of help under 5.2+ seems to help in most
cases here.

[debug_linux.sh]
#!/bin/sh

LIBS="/lib/libdl.so.2 /lib/libpthread.so.0 /lib/libm.so.6 /lib/libc.so.6 /lib/ld-linux.so.2 /lib/libnss_files.so.2 /l
ib/libnss_dns.so.2 /lib/libresolv.so.2 /lib/libdl.so.2 /lib/libpthread.so.0 /lib/libm.so.6 /lib/libresolv.so.2 /lib/l
ibnss_dns.so.2 /lib/ld-linux.so.2 /lib/libnss_files.so.2"

for i in $LIBS; do
    if [ ! -e $i ]; then
        ln -s /usr/compat/linux/$i $i
    fi
done
[/debug_linux.sh]
