Ok, that made complete sense, Figured that out (dbx:multproc on)
It passes to the child and moves along a little, then....
Here's what happens:(dbx) next
trace in nsmain.c: 394 nsconf.nsd = (char *) Tcl_GetNameOfExecutable();
stopped in Ns_Main at line 394 in file
"/aolserver_devel/aolserver-4.0-beta10-src/nsd/nsmain.c" ($t1)
394 nsconf.nsd = (char *) Tcl_GetNameOfExecutable();
(dbx) next
trace in nsmain.c: 395 NsConfigEval(config, argc, argv, optind);
stopped in Ns_Main at line 395 in file
"/aolserver_devel/aolserver-4.0-beta10-src/nsd/nsmain.c" ($t1)
395 NsConfigEval(config, argc, argv, optind);
(dbx) next
Illegal instruction in . at 0x0 ($t1)
0x00000000 00000000 Invalid opcode.
(dbx) next
Illegal instruction in . at 0x0 ($t1)
0x00000000 00000000 Invalid opcode.
(dbx) next
Line 396 is:
ns_free(config);
I've tried stack size up to 1Mb and as low as 65k, same results. System is
43P150 375MhzPowerPc with 1GbRam and 2Gb paging(swap).
Thanks.
