Bug #: 55697
Summary: Another ice in remove_redundant_iv_tests
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dcb314@hotmail.com
Created attachment 28969

C source code
I just tried to compile the package freetds-0.91-5
on gcc-4.8 trunk dated 20121212 on an AMD x86_64 box.
The compiler said
convert.c: In function 'string_to_numeric':
convert.c:1939:1: internal compiler error: in remove_redundant_iv_tests, at
tree-ssa-loop-ivcanon.c:559
string_to_numeric(const char *instr, const char *pend, CONV_RESULT * cr)

This looks like a different bug report to # 55208.

Reduced:
markus@x4 tmp % cat test.i
int a[0];
int
fn1 ()
{
int *b=0;
int i, j=0;
do
{
int n = *b++;
for (i = 0; i < 1; ++i)
n = *b++;
a[++j] = n - '0';
b -= 6;
}
while (b);
return 0;
}
markus@x4 tmp % gcc -c -O2 test.i
test.i: In function ‘fn1’:
test.i:3:1: internal compiler error: in remove_redundant_iv_tests, at
tree-ssa-loop-ivcanon.c:559
