core file missing part of call stack

It seems that since the Upgrade from aix 4.3 to 5.2 the corefiles are somehow truncated.
I tried the debuggers ddd, xldb and gdb everytime the same results.

i found this on the IBM site:
IBM Information center:
If some entries appear in the Call Stack monitor but others are missing, this indicates that the process call stack has an entry for a function contained within a module that is not available. This situation causes the call stack to be truncated in the monitor; that is, only the entries in the stack up to that entry are shown.

This is exactly my problem. I only see the upper part of the stack.
But how can i solve this Problem ?

this is what my Stack looks like:

xldb -co myExe&

pthread_kill()
_p_raise()
raise()
abort()
mysighandler()
0x00000282234a <--- this is where the call stack with the Sig11 should be
FunctionWhichForksTheProcessWithSig11()
main()

any hints or tipps ?

ddd --dbx works :slight_smile:
