My post belongs to "no forum" , but is still reachable.
Don't know why it lost the compiler forum tag.
Building main.c in fatfs avr-complex:
main.c:699:1: internal compiler error: in push_reload, at reload.c:1360
https://www.avrfreaks.net/forum/f...
Could a kind mod :-)
Move this thead to the Compiler forum
I wonder how i got it posted without a forum at all.

I just put a #if 0 around the body of everything within main() and then it compiled. So I guess one could use a binary split technique there to find out what it is in main() that the compiler does not like.
EDIT: it's something under the top level case 'f':
EDIT2: OK it's something in this case:
case 'l' : /* fl [<path>] - Directory listing */
while (*ptr == ' ') ptr++;
res = f_opendir(&Dir, ptr);
if (res) { put_rc(res); break; }
p1 = s1 = s2 = 0;
for(;;) {
res = f_readdir(&Dir, &Finfo);
if ((res != FR_OK) || !Finfo.fname[0]) break;
if (Finfo.fattrib & AM_DIR) {
s2++;
} else {
s1++; p1 += Finfo.fsize;
}
xprintf(PSTR("%c%c%c%c%c %u/%02u/%02u %02u:%02u %9lu %s"),
(Finfo.fattrib & AM_DIR) ? 'D' : '-',
(Finfo.fattrib & AM_RDO) ? 'R' : '-',
(Finfo.fattrib & AM_HID) ? 'H' : '-',
(Finfo.fattrib & AM_SYS) ? 'S' : '-',
(Finfo.fattrib & AM_ARC) ? 'A' : '-',
(Finfo.fdate >> 9) + 1980, (Finfo.fdate >> 5) & 15, Finfo.fdate & 31,
(Finfo.ftime >> 11), (Finfo.ftime >> 5) & 63,
Finfo.fsize, &(Finfo.fname[0]));
#if _USE_LFN
for (p2 = strlen(Finfo.fname); p2 < 14; p2++)
xputc(' ');
xprintf(PSTR("%s\n"), Lfname);
#else
xputc('\n');
#endif
}
if (res == FR_OK) {
xprintf(PSTR("%4u File(s),%10lu bytes total\n%4u Dir(s)"), s1, p1, s2);
if (f_getfree(ptr, (DWORD*)&p1, &fs) == FR_OK)
xprintf(PSTR(", %10luK bytes free\n"), p1 * fs->csize / 2);
}
if (res) put_rc(res);
break;
EDIT3: As you may have guessed it's that rather complex looking xprintf() in the middle of that.

Thanx Cliff & Joey
Now i know it's not only my TC's that crashes.
I'll just drop the ugly xprintf , and get on.

Well i had to try if the bug still exists with 4.9.2 , and it does
