#811: Bus error encrypting/decrypting with OpenSSL -------------------------------+-------------------------------------------- Reporter: pwilson@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.7 Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- I've verified that Trac 809 fixes an OpenSSL bug I ran into, but I'm running into additional failures later in the process of doing encryption/decryption operations. I'm attaching a test file that first encrypts some data with an RSA key and then decrypts it. On encryption, the script bus errors with this stack trace: {{{ Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x0000000100972cd8 0x00007fff84444289 in BN_bn2bin () (gdb) bt #0 0x00007fff84444289 in BN_bn2bin () #1 0x00007fff844b0634 in RSA_eay_public_encrypt () #2 0x00007fff844c4c6b in RSA_public_encrypt () #3 0x0000000103d1ad79 in ossl_rsa_public_encrypt () #4 0x00000001001408e9 in rb_vm_dispatch () #5 0x0000000103a00d50 in ??

Ie... {{{ - str = rb_str_new(0, out_len); + str = rb_bstr_new(); + rb_bstr_resize(str, out_len); }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/811> MacRuby <http://macruby.org/>
