| Description: |
Tcl/Tk: 8.4a5, cvs on Apr.29.2002. Platform: Tru64Unix V5.1 / Alpha Thread enabled The same results with gcc and cc (1) If tcl/tk is built with thread enabled, tcltest passes tcl/tests. However, the interpreter crashes in tktest like this. (in tk/unix) make test ... config.test alloc: invalid block: 1400a4430: 54 54 74 /bin/sh: 680284 Abort - core dumped --- ./tktest ../tests/config.test -verbose psb ... ++++ config-12.17 PASSED ++++ config-13.1 PASSED alloc: invalid block: 14009ebf0: cd 0 74 Abort (core dumped) (2) If I run a part of the test, it does not crash. ./tktest ../tests/config.test -verbose psb -match 'config-1[23]*' ... ++++ config-13.1 PASSED config.test: Total 158 Passed 18 Skipped 140 Failed 0 (3) If I compile tcl without -DUSE_THREAD_ALLOC=1, tcl/tk passes tests as before. ----- Kazuro Furukawa. | |||
