Re: [DynInst_API:] PIE segfault

[Bill Williams <bill@xxxxxxxxxxx>]

Known issue in 9.1, but this should be fixed on github's master. Is this not the case?

Subject: [DynInst_API:] PIE segfault

 

In the latest version of Dyninst, rewriting a PIE binary (not a library) results in an executable that immediately segfaults. This happens even if no instrumentation was done at all. Simply opening the binary and saving it reproduces the problem. Here's a sample backtrace: 

dl_main at rtld.c:172

_dl_sysdep_start at ../elf/dl-sysdep.c:249

_dl_start_final at rtld.c:332

dl_start at rtld.c:558

_start() from /lib64/ld-linux-x86_64.so.2

I am having this issue on both Ubuntu 14.04 and Ubuntu 16, the x86_64 versions.

Any clue? 

Thanks.
