A tale of an impossible bug: big.LITTLE and caching
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.htmlToo bad however that the kernel patchset mentionned in a previous post only covers arm64..So it's still a problem from arm32.
