Some code snippet:
I am able to print out values of DBSecTime on every sprintf until I reach the sql statement, following which, a Bus error(coredump) will appear.
Hope someone is able to give me some advices. Thanks in advance.

Hi!
I've got a program which runs fine under Linux, but I have compiled it to run under SunOS 5.8 in a Sparc computer, and now it sometimes fails with "bus error".
Ussing gdb I surfed to the error line, which is

where some_vector is a 16 byte struct (4 integers)... (1 Reply)

crc32
CRC32(3) 1 CRC32(3)crc32 - Calculates the crc32 polynomial of a stringSYNOPSIS
int crc32 (string $str)
DESCRIPTION
Generates the cyclic redundancy checksum polynomial of 32-bit lengths of the $str. This is usually used to validate the integrity of data
being transmitted.
Warning
Because PHP's integer type is signed many crc32 checksums will result in negative integers on 32bit platforms. On 64bit installa-
tions all crc32(3) results will be positive integers though.
So you need to use the "%u" formatter of sprintf(3) or printf(3) to get the string representation of the unsigned crc32(3) checksum
in decimal format.
For a hexadecimal representation of the checksum you can either use the "%x" formatter of sprintf(3) or printf(3) or the dechex(3)
conversion functions, both of these also take care of converting the crc32(3) result to an unsigned integer.
Having 64bit installations also return negative integers for higher result values was considered but would break the hexadecimal
conversion as negatives would get an extra 0xFFFFFFFF######## offset then. As hexadecimal representation seems to be the most common
use case we decided to not break this even if it breaks direct decimal comparisons in about 50% of the cases when moving from 32 to
64bits.
In retrospect having the function return an integer maybe wasn't the best idea and returning a hex string representation right away
(as e.g. md5(3) does) might have been a better plan to begin with.
For a more portable solution you may also consider the generic hash(3). hash("crc32b", $str) will return the same string as
dechex(crc32($str)).
PARAMETERS
o $str
- The data.
RETURN VALUES
Returns the crc32 checksum of $str as an integer.
EXAMPLES
Example #1
Displaying a crc32 checksum
This example shows how to print a converted checksum with the printf(3) function:
<?php
$checksum = crc32("The quick brown fox jumped over the lazy dog.");
printf("%u
", $checksum);
?>
