--- Comment #7 from Rainer Orth <ro at gcc dot gnu.org> ---
Unfortunately, the issue persists on current trunk:
32-bit-default gccgo, sparc-sun-solaris2.11 (SPARC S7-2):
real 3:07.71
user 3:05.92
sys 0.89
32-bit-default gccgo, sparc-sun-solaris2.11 (SPARC T8-1):
real 1:18.05
user 1:16.50
sys 0.38
Given that the compile time is close to the default limit (5m) even on an
unloaded machine, the test is almost guaranteed to FAIL under load.
