Hello.

I am writing a complex Bash script which on failure prints a stack
trace.  After upgrading to Bash 5.3.0 I noticed a strange change of
behaviour in BASH_SOURCE which I believe is a bug.

I can't reproduce it. Using your script, I get

$ ./bash ./f-g
BASH_VERSION: 5.3.0(210)-maint
FUNCNAME:     'f' 'g' 'g' 'g' 'g' 'main'
BASH_SOURCE:  './f-g' './f-g' './f-g' './f-g' './f-g' './f-g'
$ ../bash-5.3-patched/bash ./f-g
BASH_VERSION: 5.3.3(1)-release
FUNCNAME:     'f' 'g' 'g' 'g' 'g' 'main'
BASH_SOURCE:  './f-g' './f-g' './f-g' './f-g' './f-g' './f-g'
$ ../bash-5.3/bash ./f-g
BASH_VERSION: 5.3.0(2)-release
FUNCNAME:     'f' 'g' 'g' 'g' 'g' 'main'
BASH_SOURCE:  './f-g' './f-g' './f-g' './f-g' './f-g' './f-g'

using the current devel version, bash-5.3 patchlevel 3, and bash-5.3 as
released, respectively.
