bash: Disable custom memory allocator
Bash is failing trying to allocate memory [1] using the custom memory allocator if we disable it the issue is fixed. The major distributions also disabled by default [2], so we don't have a good reason to use it. The underlying issue is due to bash’s malloc using brk() calls to allocate memory, which fail when address randomization is enabled in kernel. sbrk() based custom allocators are obsolete. There may be some performance impact of this however correctness is more important.
