libcurl-7.60.0-r0 introduced symbol name conflict with libssl.so
I don’t know why, but the libcurl-7.60.0-r0 breaks our PHP 5.5.1 php-fpm application:
[21-May-2018 23:34:43.100700] DEBUG: pid 523, fpm_got_signal(), line 76: received SIGCHLD
[21-May-2018 23:34:43.100751] WARNING: pid 523, fpm_children_bury(), line 252: [pool www] child 540 exited on signal 11 (SIGSEGV) after 10.400554 seconds from start
When I restore the /usr/lib/libcurl.so.4.5.0 file with the previous version (from libcurl-7.59.0-r0) the problem disappears.
