I've traced it to this:
------- pdftoepdf.cc ------
static void copyName(char *s)
{
    pdf_puts("/");
    for (; *s != 0; s++) {
        if (isdigit(*s) || isupper(*s) || islower(*s) || *s == '_' ||
            *s == '.' || *s == '-' || *s == '+') {
                do {
                  pdfroom(1);
                  pdfbuf[pdfptr++] = c;
                } while (0);
        else
            pdf_printf("#%.2X", *s & 0xFF);
    }
}
--------------------------
debugging this I get
--------------------------
Breakpoint 1, copyName (s=0x2329380 "F15") at
../../../../src/texk/web2c/pdftexdir/pdftoepdf.cc:286
286         pdf_puts("/");
(gdb) n
Current language:  auto; currently c++
287         for (; *s != 0; s++) {
(gdb) display pdfptr
1: pdfptr = 302
(gdb) n
288             if (isdigit(*s) || isupper(*s) || islower(*s) || *s == '_' ||
1: pdfptr = 302
(gdb)
291         pdfroom(1);
1: pdfptr = 302
(gdb)
292         pdfbuf[pdfptr++] = *s;
1: pdfptr = 302
(gdb)
287         for (; *s != 0; s++) {
1: pdfptr = 4294967598
(gdb)
--------------------------
What's going on?
