When I run 'make test' it gets to this point and enters an infinite loop it appears:

PASS jpeg <--> gd1/gd2 conversion test [ext/gd/tests/jpg2gd.phpt]

I've also verified this in php5.2-200706061230.

Here's a gdb backtrace:

Expected result:
----------------
I expect the test to either PASS or FAIL and 'make test' to continue.

Actual result:
--------------
TEST 1061/2667 [ext/gd/tests/libgd00086.phpt]
Fatal error: Out of memory (allocated 1611661312) (tried to allocate 1610350689 bytes) in /apps/home/long/src/php-5.2.3-ap2/run-tests.php on line 882
