Confirmed, ICEs in vectorizer pass on x86_64-pc-linux-gnu. Reduced testcase:
--cut here--
extern int ReadBlobByte (void);
void ReadRLEImage (unsigned char *p)
{
unsigned char background_color[256];
long j;
unsigned long number_planes = ReadBlobByte();
for (j = 0; j < (long) number_planes; j++)
*p++ = background_color[j];
}
--cut here--
gcc -O2 -ftree-vectorize t.c
t.c: In function ?ReadRLEImage?:
t.c:4: error: incorrect sharing of tree nodes
prologue_after_cost_adjust.22_33 = (long unsigned int) D.1550_3;
(long unsigned int) D.1550_3;
t.c:4: internal compiler error: verify_stmts failed
Please submit a full bug report,
