That error comes from GDB while trying to access 'errno', which is a
thread-local variable. We still don't know the value of 'errno'.
As a temporary hack, you could replace the call to 'scm_encoding_error'
at strings.c:2106 with a call to 'printf' that prints out the value of
'errno'.
I guess that both iconv and gdb are somewhat broken on your system.
Thanks,
