This is the debug of last varcharout routine:

Breakpoint 1, varcharout (fcinfo=0xbf8a1e7c) at varchar.c:441
441             VarChar    *s = PG_GETARG_VARCHAR_P(0);
440     {
(gdb) print fcinfo
$25 = (FunctionCallInfo) 0xbf8a1e7c
441             VarChar    *s = PG_GETARG_VARCHAR_P(0);
446             len = VARSIZE(s) - VARHDRSZ;
(gdb) print s
$28 = (VarChar *) 0xb5ebf024
447             result = palloc(len + 1);
(gdb) print len
$29 = -4
(gdb) next
Warning:
Cannot insert breakpoint -43.

I know that something doing wrong, but I can't find out what is it.

Getting a stack trace from the point of the errfinish call would
probably help narrow it down.  One thing that's not clear is whether
SPI_modifytuple itself is failing (have you checked all the *other*
arguments you're passing it?) or whether it happens later.
