Subject: x86_64 segfault error codes
Date: Wed, 14 Dec 2005 11:17:00 -0700 [thread overview]
Message-ID: <8746466a0512141017j141d61dft3dd2b1ab95dc2351@mail.gmail.com> (raw)
For segfault error codes on x86_64, bits 0-3 are documented in
arch/x86_64/mm/fault.c. However, I am getting error 0x14 and 0x15 with this
particular user app when it segfaults. Is bit 4 valid and what does that
imply?
xxx-001[2085]: segfault at 0000007f960ea86b rip 0000007f960ea86b rsp
0000007fbfffe968 error 14
xxx-001[2091]: segfault at 0000007fbfffe670 rip 0000007fbfffe670 rsp
0000007fbfffe668 error 15
