You may want to look at https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction
which talks about how to reduce a testcase.  In particular getting the
number of input objects reduced by using -r at link time may help (if the
bug reproduces then...).  If you manage to reduce to a single input source
you can use standard reduction tools like creduce or delta to reduce
(and obfuscate) the testcase.
