Bug ID: 61250 Summary: Random pch failures on x86_64-apple-darwin13. Product: gcc Version: 4.10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: pch Assignee: unassigned at gcc dot gnu.org Reporter: dominiq at lps dot ens.fr CC: iains at gcc dot gnu.org Host: x86_64-apple-darwin13 Target: x86_64-apple-darwin13 Build: x86_64-apple-darwin13 When running the test suite on x86_64-apple-darwin13 with -j8 (4 cores, 8 threads), I see random failures for the tests g++.dg/pch/pch.C gcc.dg/pch/save-temps-1.c They are either an ICE: Internal compiler error: Error reporting routines re-entered. (may be related to pr59877), or a "program timed out" leading to an "assembly comparison": WARNING: program timed out. FAIL: g++.dg/pch/pch.C -g -I. -Dwith_PCH (test for excess errors) FAIL: g++.dg/pch/pch.C -g assembly comparison AFAICT these failures occur for any set of options or -m32/-m64. The number of failures ranges from 0 to 4/5 and seems (weakly) correlated to the machine load (-j8+backup).
