Apparently fixed in CVS then. (and in 5.2.6, once it's released :)
Reopen if this is not the case.

php-5.2.6RC5 seems to solve this issue. Just tested with -O2
optimizations and the testcase returns the expected result.

More info:
Upgraded to gcc-4.2.3 to check for possible gcc-related issue.
Recompiled entire system overnight. Problem persists.
Since the last response from a php devver is almost 6 months back, it
would be very welcome to see some response on these latest additions.

Just did a final test and recompiled php with gcc optimization set to
-O1 instead of -O2 used in previous tests, and i can confirm that
compiling with -O1 eliminates the problem aswell.
So to summarize:
-changing this_fd from int to long eliminates the problem
-compiling without openssl eliminates the problem, though this is
obviously not an option in most cases
-compiling without gcc optimizations eliminates the problem
So now the question is, is this a gcc, a php or a openssl problem?
I'm willing to test and provide you with all necessary information.

Problem persists in 5.2.6RC4.
Tested using the testcase above, on a freshly installed Athlon64 Gentoo
system. Tested against the following openssl versions:
openssl-0.9.8g
openssl-0.9.8e
openssl-0.9.7i
Recompiled php-5.2.6RC4 ebuild after each openssl version change. All
versions exhibit same erroneous behavior, as described in the initial
bugreport.
Compiling php without openssl support eliminates the problem, as
reported earlier.

This is stil a pretty serious issue on x86_64. Just ran into this one
while swapping out a bunch of x86 webservers for new x86_64 boxes.
Both the new and the old boxes run Gentoo, with the same gcc version,
same php version. The 32 bit boxes were fine, the new 64 bit boxes fail
on all stream fread's due to this issue.
