Hi Petr,
thank you for running PCRE2 on many environments.

I tried RunTest in my qemu emulated ARM-64 environment (I don't have access to real hardware), and it worked. Hence I definitely need some help to fix this. My ARM-64 GCC is Linaro 4.8.3, and I can only compile PCRE in static mode, otherwise qemu does not work.
It is interesting that test1 runs correctly, and test2 fails. Perhaps a stack related issue? The message "bus error" is also interesting, not the usual "segmentation fault". I don't know this error, but according to wikipedia, a bus error is a fault raised by hardware when a process is trying to access memory that the CPU cannot physically address.
Could you run pcre2_jit_test as well? RunTest accepts test numbers between 1 and 18, e.g: "RunTest 1 7 9 17". Could you check which tests are fail besides test2?

Zoltan
