Hi All, I'm experiencing an intermittent crash with TLSv1.3. Despite my efforts to analyze it using Valgrind or Purify, I'm unable to replicate the issue. Does anyone have any insights into this?? #0 0x0000724208ea1743 in unlink_chunk (p=p@entry=0x7241ec4c9550, av=0x7241ec000030) at ./malloc/malloc.c:1634 #1 0x0000724208ea462b in _int_malloc (av=av@entry=0x7241ec000030, bytes=bytes@entry=80) at ./malloc/malloc.c:4307 #2 0x0000724208ea5139 in __GI___libc_malloc (bytes=80) at ./malloc/malloc.c:3329 #3 0x00005a11a31f06ce in CRYPTO_zalloc () #4 0x00005a11a318d321 in bn_expand2 () #5 0x00005a11a318feab in BN_lshift1 () #6 0x00005a11a32e0481 in BN_mod_lshift1_quick () #7 0x00005a11a31b5f35 in ossl_ec_GFp_simple_ladder_step () #8 0x00005a11a31ad34d in ossl_ec_scalar_mul_ladder () #9 0x00005a11a31addf1 in ossl_ec_wNAF_mul () #10 0x00005a11a31abc3d in EC_POINT_mul () #11 0x00005a11a31a8d7f in ossl_ec_key_simple_generate_key () #12 0x00005a11a31a8061 in ossl_ec_key_gen () #13 0x00005a11a31a7fce in EC_KEY_generate_key () #14 0x00005a11a3297b38 in ec_gen () #15 0x00005a11a31d6c2b in evp_keymgmt_util_gen () #16 0x00005a11a31e2aa7 in EVP_PKEY_generate () #17 0x00005a11a311a317 in ssl_generate_pkey_group () #18 0x00005a11a31462bc in tls_construct_ctos_key_share () #19 0x00005a11a31443c3 in tls_construct_extensions () #20 0x00005a11a314f92d in tls_construct_client_hello () #21 0x00005a11a314e667 in state_machine () #22 0x00005a11a3125184 in SSL_do_handshake () .....
