Hello, all

Our device runs on Linux system . Now we are upgrading to latest code of main branch(https://github.com/google/breakpad/commit/41b6533e5f3dd7f0320ef58608ee32e8e4f132fb). The latest breakpad works fine in our 64 bit devices but crashes on our 32 bit devices during constructor of ExceptionHandler. Below is the backtrace of 3 different process. I doubt it related to memory alignment but not sure where is the potential code and how to fix it. Could you help to check on it? Very appreciated for your help!
 
Thanks and Regards
Eva
