Hi, I'm trying to run the test suite on the master branch. These are the commands I ran by following https://gcc.gnu.org/contribute.html: $ make bootstrap $ make -k check -j22 I added -j22 to utilise all my CPU cores. However, I'm encountering some test failures even when I didn't change anything in the code. Is this expected/normal? Here are some of the test failures: FAIL: gfortran.dg/bound_4.f90 -O0 (internal compiler error: 'verify_gimple' failed) FAIL: gfortran.dg/bound_4.f90 -O0 (test for excess errors) Running /home/zliew/_stuff/repos/gcc/gcc/testsuite/g++.dg/bprob/bprob.exp ...

In order to test the patch, I'm trying to run the testsuite before and after the patch, during which I encountered these failures.
