            Bug ID: 80209
           Summary: libgo test failure, dir gotest$$ not found
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

At r246482, testing with:
...
make -k -j13 check RUNTESTFLAGS="--target_board='unix/ unix/-m32'"
...

I run into:
...
/home/vries/gcc_versions/data/ref-master-17-03-26/src/libgo/testsuite/gotest:
line 169: cd: gotest19618: No such file or directory
file libcalls.go not found
FAIL: syscall
...

In gotest we see the source of the cd:
...
   165  DIR=gotest$$
   166  rm -rf $DIR
   167  mkdir $DIR
   168  
   169  cd $DIR
   170  mkdir test
   171  cd test
   172  
   173  if test $keep = false; then
   174    trap "cd ../..; rm -rf $DIR" 0 1 2 3 14 15
   175  else
   176    trap "cd ../..; echo Keeping $DIR" 0 1 2 3 14 15
   177  fi
...


I'm not familiar enough with the libgo test infrastructure to say whether:
- there could be an underlying problem, or 
- we can disregard this as a filesystem failure or some such.
