Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Because of this, we hope you add your comments to the original bug instead. Thank you for your interest in MySQL. There is only architecture difference with bug #20145. This bug is not reproducible on Solaris 9 and Solaris 10.
Description: auto-config doesn't setup HAVE_SYS_ERRLIST. so perror core dumps at unknown_error= malloc(strlen(msg)+1); Plus, I think it's not safe to have code like below /* On some system, like NETWARE, strerror(unknown_error) returns a string 'Unknown Error'. To avoid printing it we try to find the error string by asking for an impossible big error message. */ msg= strerror(10000); /* msg could be set to NULL under some platforms * then strlen would core . */ /* Allocate a buffer for unknown_error since strerror always returns the same pointer on some platforms such as Windows */ unknown_error= malloc(strlen(msg)+1); How to repeat: use default config build under solaris 2.8 Suggested fix: /* On some system, like NETWARE, strerror(unknown_error) returns a string 'Unknown Error'. To avoid printing it we try to find the error string by asking for an impossible big error message. */ msg= strerror(10000); /* msg could be set to NULL on some platforms * e.g solaris 2.8 */ if (NULL==msg) msg="Unknown Error"; /* Allocate a buffer for unknown_error since strerror always returns the same pointer on some platforms such as Windows */ unknown_error= malloc(strlen(msg)+1);
