Thanks for the prompt reply Daniele :-)

The lsusb -vvv output for the phone (run as root) is attached.

Permissions in the build directory prevented running gnokii as the
ordinary user so I ran as root and it worked:

I changed the ownership of the build directory files and reproduced the
problem as the ordinary user:

I tried to do the same under gdb but:

The libraries were not stripped in the build.  I should have written
"executables and shared object libraries".  They were not present with
the names you suggested so I searched for likely candidates and checked
them:

address@hidden:~# find / -type f -name '*libgnokii*'
/usr/lib64/libgnokii.la
/usr/lib64/libgnokii.so.7.0.0
address@hidden:~$ file -L /usr/lib64/libgnokii.la /usr/lib64/libgnokii.so.7.0.0
/usr/lib64/libgnokii.la:       libtool library file,
/usr/lib64/libgnokii.so.7.0.0: ELF 64-bit LSB shared object, x86-64,
version 1 (SYSV), dynamically linked, not stripped

Best
