This fix seems to be a twin of v2015.01 commit 854d2b9753e4 ("dlmalloc: ensure gd is set for early alloc"). Here is a gdb backtrace to make them look even more similar (sandbox build):

Interestingly, this issue appears on a very old v2015.04 U-boot, but not on u-boot/master (even if the fix applies cleanly to u-boot/master). With the patch applied, my ancient u-boot starts to work properly:
That's probably because of 2f0bcd4de1ab0cb03f01428a334cd91f8870504c "malloc: use hidden visibility" which prevents code outside of U-Boot from using U-Boot's malloc/free?
(I only remember this because I very recently bisected an issue in an old branch that caused sandbox crashes after upgrading the OS on a test machine and triggering the bug that commit fixes.)
