Crash in gum_backtracer_make_accurate #1065
Description
Hi, when I use gum_backtracer_make_fuzzy, all retaddrs[i] point to the same value, which is the callout function. Why is that?
and when I use gum_backtracer_make_accurate , I get a SEGV:
#0 access_mem (as=<optimized out>, addr=4294967256, val=0xffffffffde60, write=0,
arg=<optimized out>) at ../../../libunwind/src/aarch64/Ginit.c:337
