I'm going to backup a bit; so another question...
This test is a fairly simple test that should not be taxing on GC or any other resource so I'm surprised the the default configuration is not sufficient.  It might be worth looking a bit deeper into the GC vs Xcomp conditions and the interplay with "looongaarch64".
I can't help much there, not being familiar with details of GC or the compiler.
