Bug ID: 18882
Summary: readelf computes undefined expression (long int) 1 <<
63
Product: binutils
Version: 2.25
Status: NEW
Severity: minor
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: zeccav at gmail dot com
Target Milestone: ---
Running the gas testsuite with a gnu gcc sanitized version of readelf
I got the following sanitizer message
readelf.c:1569:37: runtime error: left shift of 1 by 63 places cannot be
represented in type 'long int'
the offending statement in readelf.c:1569 is
if (off == ((bfd_signed_vma) 1) << ((sizeof (bfd_signed_vma) * 8) - 1))
that tries to compute (long int) 1 << 63
but this is undefined.
Maybe it should be (unsigned long int) 1 << 63
