Bug #: 14933
Summary: ar & ranlib generate truncated files on 32bit
platform.
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: al...@fairlite.co.uk
Classification: Unclassified
Hi,
Just moved from binutils 2.22 to 2.23 and ar & ranlib generated bad archives
with the message "file truncated".
Looking into the problem reveals that in archive.c we have at around line
2414....
file_ptr firstreal;
....
file_ptr max_first_real;
max_first_real <<= 31;
then later we do....
/* The archive file format only has 4 bytes to store the offset
of the member. Check to make sure that firstreal has not grown
too big. */
if (firstreal >= max_first_real)
{
bfd_set_error (bfd_error_file_truncated);
return FALSE;
}
I added a check that did this in the errored function.
printf("CHECK %d %d (%d)\n",firstreal,max_first_real,sizeof(file_ptr));
It came back with....
CHECK 104 -2147483648 (4)
So, shouldn't firstreal/max_first_real be ufile_ptr's ?
