I had this problem too with GDB on the Odroid UX4 big.LITTLE SoC.

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.
