Slowly, I've been able to run this in "dbx" (the equivalent to gdb on Solaris)
and got the following backtrace:
t@1 (l@1) stopped in encode_with_iconv (optimized) at line 573 in file "utils.c"
573 *(unsigned char *)inptr);

I'll note that running with TEXINFO_XS=omit doesn't give the error message.
