This section presents the error messages that can occur during the execution of C and
C++ programs. The Common Run-Time Environment (CRE) emits these messages.
For more details on the error messages and the CRE, see the Common Run-Time
Environment (CRE) Programmer’s Guide.
Trap and Signal Messages
The TNS CRE reports the messages in this subsection if a trap occurs and your
program has neither disabled traps nor enabled its own trap handler. The native CRE
reports the messages in this subsection if a signal is raised and your program does not
have its own signal handler for the signal that was raised. The CRE or run-time library
terminates your program.
The CRE treats trap 4, arithmetic fault, as a program logic error, not a trap. If your
program has disabled overflow traps, the TNS CRE returns control to your run-time
library. The native CRE raises a SIGFPE signal instead. For additional detail, see the
language-specific manuals for the routines in your program for additional detail. The
Guardian Programmer’s Guide describes traps and signals.

data area allocated to the process.
