I'm not too familiar with Illumos, any chance you could get the exact line number using gdb or perhaps gaddr2line?

[jussisallinen]

@rgacogne Here's gdb bt:

Hello

I had a similar crash under solaris 11.3 and found out that problem was in using byte ordering function with IN in name (BE_IN64 for example). This functions require pointer to integer as argument instead integer.

Path is attached.

Hi @skolot, thank you for this patch! Would you be willing to turn that into a pull request so your name appear in the log? If so, could you please add parentheses to prevent any surprises later, ie replacing BE_IN16(&x) with BE_IN16(&(x)) and so on.

[rdayneko]

@rgacogne, done #4877

BE_IN16(&(x))

i completely forgot that i'm working with macros, thank you (:

[rgacogne]

Thanks!

[Habbie]

Can we close this now that #4877 has been merged?

[jussisallinen]

@Habbie This can now be closed, PowerDNS will be included in SmartOS pkgsrc 2017Q1.

[Habbie]

@jussisallinen thanks!
