Line 1111 or Illegal instruction error

[Gabo]

I'm making some test with hackmaster and write this code t try to show an 
alert for cheking error, but when run on emulator always give me an error 
"line 1111" or "illegal instruction", but if I remove the call to the 
routine ShowMyError it work fine.What am I doing wrong?

Any suggestion will be great.
Gabo.

I make with this commands:

m68k-palmos-gcc -O1 -palmos3.5 -nostartfiles -o code03e8 code03e8.c
m68k-palmos-obj-res code03e8
cp code0001.code03e8.grc code03e8.bin
build-prc -t HACK myhack.prc "myhack" slid   *.bin

The code is:

#include <PalmOS.h>
#include <PalmCompatibility.h>
#include "sliderhack.h"

void ShowMyError(Char *s1,Char *s2,Char *s3);


void MyEvtGetEvent(EventPtr evento, Int32 tiempo)
{
    DWord               temp;
    void              (*oldTrap)(EventPtr, Int32);
  

    FtrGet('slid', 1000, &temp);
    oldTrap = (void (*)(EventPtr, Int32)) temp;
    
    ShowMyError("a","b","c");

    oldTrap(evento, tiempo);
}




void ShowMyError(Char *s1,Char *s2,Char *s3)
{
DmOpenRef dbref;
UInt16 button;
    
    
    dbref = DmOpenDatabaseByTypeCreator('HACK','slid',dmModeReadOnly);

    if (dbref) {
        button=FrmCustomAlert(ErrorA,s1,s2,s3);
        DmCloseDatabase(dbref);
        }
}
