Starting with selftest::run_tests(), these tests need to be run to
trigger it, all others can be omitted:

ggc_tests_c_tests ();
input_c_tests ();
gimple_c_tests ();
rtl_tests_c_tests ();
read_rtl_function_c_tests ();
--> forcibly_ggc_collect ();

In this constellation, we have on the stack:

No, can you see which collect call in the self-test is involved?
That is, a better backtrace, eventually when compiling the testcase
with -O0?

This caused (or uncovered) a self-test issue on arm-netbsdelf (as run
by config-list.mk), like in this build:

Reverting your patch from current HEAD lets the self-test pass. Do you
spot something obvious?
