Thank you for reproducing the issue Andreas! Any suggestions on how to get to the core of it? I have not gotten an attack plan yet, so open to any recommendations ;)
Cagdas -----Original Message----- From: gem5-dev [mailto:[email protected]] On Behalf Of Andreas Sandberg Sent: Monday, July 06, 2015 6:41 AM To: gem5 Developer List Subject: Re: [gem5-dev] X86 FS regression test fails on OSX with "Abort trap: 6" error Cagdas, I just tried to run the quick x86 regressions using a gem5 compiled with clang 3.5 on Linux and ran into a similar problem. In my case, the tests segfault, but all the other symptoms seem identical. An interesting observation is that /all/ the other backends run their quick regressions just fine, so I'm inclined to say that this is an x86-specific issue that is triggered by clang (I'm assuming you're using clang since you're on MacOS). //Andreas On 30/06/2015 23:13, Cagdas Dirik (cdirik) wrote: > Thank you for suggestions Nilay and Andreas! > > Andreas, I looked at the simerr and simout files, and there are no > indications of a missing file.
