[ruby-core:78439] [Ruby trunk Bug#12993] SEGV in OpenSSL::TestSSL#test_close_after_socket_close

Issue #12993 has been updated by Kazuki Yamaguchi.


Not really a segfault but rb_sys_fail() is calling rb_bug() because errno is 0. OpenSSL 1.1.0c introduced a breaking change in SSL_read()[1], and it is already reverted in the OpenSSL-1_1_0-stable branch.

I have patched ruby/openssl[2] so that it never calls rb_sys_fail() with errno==0, like syswrite already does, but I haven't imported to trunk.

----------------------------------------
Testing the latest version of Ruby from trunk on Fedora Rawhide, the OpenSSL::TestSSL#test_close_after_socket_close segfaults (see the attached log). Not sure what might be possible the reason, if it is some change in Fedora in Ruby.
