. Reduce the problematic .el file to the minimum by bisection, and
try identifying the function that causes the problem.
. Reduce the problematic function to the minimal code that still
. Try natively compiling the problematic file with
'native-comp-speed' set to 1 or even zero. If doing that solves
the problem, you can use
(declare (speed 1))
at the beginning of the body of suspected function(s) to change
native-comp-speed only for those functions -- this could help you
identify the function(s) which cause(s) the problem.
. Reduce the problematic function(s) to the minimal code that still
reproduces the problem.
. Study the problem's artifacts, like Lisp or C backtraces, to try
