The initialize_shell_variables function is processing env. When the for loop reaches env[16], glibc needs to use the main_arena.top variable. However, the value in the address pointed to by the top variable is overwritten by env[15], causing a glibc exception and resulting in a coredump
`env' is the environment bash gets at startup.
We are still continuously find a way to reliably reproduce it, but this may take some time. We hope you could take a look at the above information and provide useful suggestions
Maybe build a version of bash with address sanitizer enabled and see if you
can trigger the problem using that version. The asan output should provide
more information.
