Hi all, (resending without attachment because the previous email got rejected) Last night I've built GHC HEAD with the default settings, and ran the testsuite with just `make`. It ran into 77 unexpected failures; the failure log is available at http://hpaste.org/82291. The summary is at the end of this email. I've fixed the Data.Typeable.Proxy ones in the meantime. The rest I don't know, but maybe some of you can relate to some of these failures. Cheers, Pedro Unexpected failures: ../../libraries/base/tests/IO hClose002 [bad exit code] (ghci,threaded1,threaded2) ../../libraries/directory/tests getPermissions001 [bad stdout] (normal,hpc,optasm,threaded1,threaded2) ../../libraries/hpc/tests/simple/tixs hpc_help_draft [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_help_markup [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_help_overlay [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_help_report [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_help_show [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_markup_error_001 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_markup_error_002 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_report_error_001 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_report_error_002 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_show_error_001 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_show_error_002 [bad stdout] (normal) ../../libraries/hpc/tests/simple/tixs hpc_version [bad stdout] (normal) ../../libraries/process/tests process007 [bad stderr] (threaded1,threaded2) ../../libraries/process/tests process007 [bad stdout or stderr] (ghci) ../../libraries/unix/tests getEnvironment02 [bad exit code] (ghci) ../../libraries/unix/tests/libposix posix005 [bad stdout or stderr] (ghci) codeGen/should_compile jmp_tbl [exit code non-0] (hpc) codeGen/should_compile massive_array [exit code non-0] (hpc) codeGen/should_run cgrun068 [bad exit code] (ghci) concurrent/should_run T5611 [bad exit code] (ghci) concurrent/should_run foreignInterruptible [bad exit code] (ghci) driver/recomp006 recomp006 [bad stderr] (normal) ffi/should_run T1679 [bad exit code] (ghci) ffi/should_run T7170 [bad stdout or stderr] (ghci) ghc-api T6145 [bad exit code] (normal) ghc-api/T4891 T4891 [bad exit code] (normal) numeric/should_run arith016 [bad exit code] (ghci) numeric/should_run expfloat [bad exit code] (ghci) parser/should_run readRun002 [bad exit code] (ghci) parser/should_run readRun004 [bad exit code] (hpc) perf/compiler T1969 [stat not good enough] (normal) perf/compiler T3064 [stat not good enough] (normal) perf/compiler T3294 [stat not good enough] (normal) perf/compiler T4801 [stat not good enough] (normal) perf/compiler T5030 [stat not good enough] (normal) perf/compiler T5321FD [stat not good enough] (normal) perf/compiler T5321Fun [stat not good enough] (normal) perf/compiler T5631 [stat not good enough] (normal) perf/compiler T5642 [stat not good enough] (normal) perf/compiler T5837 [stat not good enough] (normal) perf/compiler T6048 [stat not good enough] (optasm) perf/compiler T783 [stat not good enough] (normal) perf/compiler parsing001 [stat not good enough] (normal) perf/should_run lazy-bs-alloc [stat too good] (normal) plugins plugins01 [bad stderr] (normal) programs/andy_cherry andy_cherry [bad exit code] (ghci) programs/barton-mangler-bug barton-mangler-bug [bad exit code] (hpc,optasm,threaded2) programs/life_space_leak life_space_leak [bad exit code] (ghci) programs/seward-space-leak seward-space-leak [bad exit code] (ghci) rts stack002 [bad exit code] (threaded1,threaded2) simplCore/should_compile T4908 [stderr mismatch] (optasm) simplCore/should_compile spec-inline [stderr mismatch] (optasm) th TH_emptycase [stderr mismatch] (normal)
