All current EM implementations detect this error.
.IP "stack size of process too large"
.br
The current implementation limits the stack size of processes to 1024 bytes.
This is most likely to happen if the reserved space for a coroutine stack
is too small. In this case, increase the size of the area given to
\fCWNEWPROCESS\fP. It can also happen if the stack needed for the main
process is too large and there are coroutines. In this case, the only fix is
to reduce the stack size needed by the main process, f.i. by avoiding local
arrays.
.IP "too many nested traps + handlers"
.br
This error can only occur when the user has installed his own trap handler.
@ -395,6 +400,11 @@ The descriptor is pushed first.
If the parameter is a value parameter, the called routine must make sure
that its value is never changed, for instance by making its own copy
of the array. The Modula-2 compiler does exactly this.
.PP
When the size of the return value of a function procedure is larger than
the maximum of \fCWSIZE(LONGREAL)\fP and twice the word-size, the caller
reserves this space on the stack, above the parameters. Callee then stores
its result there, and returns no other value.
