Daniel,

Thanks for suggesting valgrind. I get the following:

==8732== malloc/free: in use at exit: 192067 bytes in 2541 blocks.
==8732== malloc/free: 287281 allocs, 284740 frees, 94694311 bytes
allocated.
==8732==
==8732== 16032 bytes in 501 blocks are definitely lost in loss record
20 of 23
==8732== at 0x3C01E9D3: calloc (vg_replace_malloc.c:141)
==8732== by 0x3C06B257: kssl_ctx_new (in /lib/libssl.so.0.9.7a)
==8732== by 0x3C05DB77: SSL_new (in /lib/libssl.so.0.9.7a)
==8732== by 0x80550A7: Curl_ossl_connect_step1 (in /root/dev/
UPCSC2/tools/a.out)

When running my test program on Mac OS X with 0.9.8e, the memory
profile is well-behaved. It would appear that OpenSSL 0.9.7a is the
culprit.

Thanks for the help!

Cheers,
