PHP Version: 5.1.2
New Comment:
After some testing- getimagesize() in 5.1.3-dev only works
with flash files that are not in SWC format.
php was compiled using:
./configure --enable-debug --with-apxs=/usr/sbin/apxs --with-
zlib=/usr

With 5.1.3-dev and zlib enabled I get this:
array(5) {
[0]=>
int(550)
[1]=>
int(400)
[2]=>
int(13)
[3]=>
string(24) "width="550" height="400""
["mime"]=>
string(29) "application/x-shockwave-flash"
}

getimagesize does not work on the test flash file in 5.1.3
dev - but does not cause crash - so I can't append a
backtrace, getimagesize returns false instead.
I can append a backtrace from a non debug php5.1.2 though.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
