Had the same issue and figured it was with CURL, which I'm upgrading now to 7.50 in hopes that it resolves the issue! I was using 7.47.1 when I got the same segmentation fault and core dump. gdb /usr/local/bin/php ~/php.core [...] (gdb) bt #0 0x0000000801b1290d in free () from /lib/libc.so.7 #1 0x00000008031fa4b5 in CRYPTO_free () from /lib/libcrypto.so.7 #2 0x0000000805e9dbb4 in SSL_CTX_set_alpn_protos () from /usr/local/lib/libssl.so.8 #3 0x000000080532dfd1 in curl_pushheader_byname () from /usr/local/lib/libcurl.so.4 #4 0x000000080533204d in curl_pushheader_byname () from /usr/local/lib/libcurl.so.4 #5 0x00000008052f310d in curl_formfree () from /usr/local/lib/libcurl.so.4 #6 0x00000008053029c1 in curl_formfree () from /usr/local/lib/libcurl.so.4 #7 0x0000000805315fed in curl_multi_perform () from /usr/local/lib/libcurl.so.4 #8 0x0000000805315bda in curl_multi_perform () from /usr/local/lib/libcurl.so.4 #9 0x00000008068ece48 in zif_curl_multi_exec () from /usr/local/lib/php/20131226/curl.so #10 0x00000000005ec334 in zend_do_fcall_common_helper_SPEC () #11 0x00000000005ad5d8 in execute_ex () #12 0x0000000000585753 in zend_execute_scripts () #13 0x000000000052dac3 in php_execute_script () #14 0x00000000006082f8 in do_cli () #15 0x000000000060717f in main () Previous Comments: ------------------------------------------------------------------------ [2016-06-02 08:03:40] daniel dot ylitalo at mytaste dot com I tried upgrading curl from 7.48 to 7.49 and that solved the segfault, sorry for not trying that before doing a report.
