Since GDB is patching the instrution with ptrace to insert a breakpoint for example.
See my blog post about it: https://www.kayaksoft.com/blog/2016/05/11/random-sigill-on-a...
Or the post on the GDB mailling list: https://www.sourceware.org/ml/gdb/2015-11/msg00030.html
Too bad however that the kernel patchset mentionned in a previous post only covers arm64..
So it's still a problem from arm32.
