What was the configure line you used?

Extra note: a build created an ran on RHEL 4 will NOT segfault when
using -i

Debug Build => yes

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.

Some things I noticed:
- Disabling the sqlite.so module will "solve" the problem. 
- when using phpinfo() on a website, there is NO segfault on from the
command line

Description:
------------
When executing php -i (php information) it shows some output but then
it will segfault.




Reproduce code:
---------------
On commandline: php -i


Expected result:
----------------
Probably missing entries

Actual result:
--------------
Segmentation faul.

Strace:
write(1, "PDO Driver for SQLite 3.x", 25PDO Driver for SQLite 3.x) =
25
write(1, " => ", 4 => )                     = 4
write(1, "enabled", 7enabled)                  = 7
write(1, "\n", 1
)                       = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
