unexpected exit
On top of that, there is another question met on HP-UX 11i v2. The running program exit unnormally and no coredump. I used the 'gdb' tool to debug , it exit and return the message:
(gdb) ttrace wait: No child processes. When using 'where' to find the breakpoint, it retruned the following messages: (gdb) where warning: reading register 324: Permission denied warning: reading register 584: Permission denied warning: reading register 585: Permission denied warning: reading register 473: Permission denied #0 0x0 in <unknown_procedure> () warning: reading register 584: Permission denied warning: Attempting to unwind past bad PC 0x0 warning: reading register 332: Permission denied warning: reading register 448: Permission denied warning: reading register 520: Permission denied #1 0x0 in <unknown_procedure> () In the program, I used the 'SYS V semphore' and POSIX 'shared memory' mechanism. The code is too long and the program is a part of our system, we are porting them to HP-UX, this error report never meet on the other OS(AIX, Solaris,True64). Anyone met and solve it? Thanks.
