Hi,

Could some expert kindly tell why the one printf statement in the
main program below causes the trouble? (I downloaded the compiler
less than 2 months ago.) Thanks in advance.

#include <stdio.h>
#include <stdlib.h>

void test()
{ int *hh;
   printf("abc\n"); free(hh); printf("def\n");
}

int main()
{ // If the following printf statement is commented out
   // then no error message ("Exiting due to signal SIGSEGU")

   printf("calling test\n");

   test();
   return 0;
}
