Crash in malloc.c : internal_malloc under Asan

Hi Everyone,

I'm trying to use an Asan-instrumented version of Bash for my shell.
Bash is dying in startup code. The source file is malloc.c (missing
from Bash sources at
https://git.savannah.gnu.org/cgit/bash.git/tree/), and the function is
internal_malloc.

The Asan folks have a suspicion of malloc.c. Also see "Crash in
application's startup code around Asan red zone",
https://groups.google.com/g/address-sanitizer/c/oB8opTbjkuw.

Where is malloc.c coming from? Where can I find it?

Jeff
