Re: [DynInst_API:] PIE segfault

[John Detter <jdetter@xxxxxxxx>]

Mohamed,

Are you sure you are using the latest master? In my version of 
arch-x86.C line 7993 isn't inside the ia32_decode function. Could you 
try pulling from master and rebuilding/rerunning? If you could provide 
another stack trace that would be really helpful.
