I couldn't replicate this with gcc 7.1.1.
Would you mind attaching your tests/elfstrmerge.o object file?

Comment 3 Mark Wielaard 2017-09-04 21:13:47 UTC 
Thanks. Replicated with that object file. But not yet understood.

Filtering -fno-plt from CFLAGS fixes the issue

Thanks. That is interesting. Would you mind also attaching the elfstrmerge.o file binary produced without -fno-plt? That would make it easier to see exactly what change in the binary causes the breakage.

Sorry for the delay, i built both with the same gcc/glibc
