gccgo: runtime address space conflict on AIX #24994
Comments

I don't think we support AIX. Can you try running your code on a linux machine ? |
|
Ah ok, so it is not supported.
It is not a bug since AIX is not supported yet. If you still see the issue once the port is complete, then we can track issues for it. Closing as this is not a bug. |

@agnivade This issue was opened against gccgo. The AIX port of gccgo is largely complete. I don't think we need to close these issues are not supported. |

That said, this bug was likely fixed by https://golang.org/cl/97357 or https://golang.org/cl/99117. @amandeepgautam Can you try a current version of gccgo? |

I see. I wasn't sure whether we track bugs for partially complete ports. Since the issue #19200 was not resolved, I concluded that it wasn't complete. Thanks for following up. |
|
@ianlancetaylor I have already set it up and will update if I still see these errors. |
|
Closing the issue as we cannot reproduce it. |
