Fix zygote crash loop on 32-bit devices (#145) - #153
Merged
Conversation
Bump LSPlt to pick up the PatchPLTEntry fix. While backing up a hook region, LSPlt left it unmapped between moving the original segment aside and mapping the writable copy in its place. That region holds libandroid_runtime.so's .got and .got.plt, and on arm32 that library is the process's only provider of __aeabi_memcpy, __aeabi_memmove and friends -- each a bare `b <sym>@plt` through its own GOT, since bionic keeps its copies hidden. Any call to them from anywhere in the process during the window faults. On a 32-bit Android 10 device this killed zygote from inside our remote entry() call, the tracer restored registers and detached without the region ever being mapped back, and zygote then died again on its next __aeabi_memmove. Magisk restarted it and the whole thing repeated, leaving the device unusable.

took a while to find the artifact :) it works!!! vector/stack loads ok, in logs only "E/" are: grep 'E/' verbose_2026-08-09T09\:37\:00.481.logand many normal lines:
