What branch did you check out?
I wonder if it is related to this change (pullup to the 2.x branch pending)

Module Name:	src
Committed By:	dsl
Date:		Mon Feb 14 20:46:26 UTC 2005

Modified Files:
	src/bin/sh: expand.c

Log Message:
expbackq() was incorrectly backing up a temporary buffer when removing \n
from the end of output of commands inside $(...) substitutions.
If the program output is n*128+1 bytes long (ending in a \n) then the code
checks buf[-1] for another \n - looking an uninitialised stack.
On a big-endian system an integer of value 10 will satisfy this (unlikely
on little endian) and can happen depending on the last code path to use
a lot of stack!
This caused the problem with newvers.sh on sparc64 after ', 2005' was
added to the date list.
Fixed PR/28852
