seg fault with repeated function calls from C? |

Hi all,
I am calling a guile function from my C code. Its a fairly straight
forward implementation. However, as I keep calling this function a
number of times, it breaks at some point with a segmentation fault. Here
is the relevant portion :
int tmp,count=10000;
for (tmp=1;tmp<count;tmp++) {
func_symbol = scm_c_lookup("EsourceFn");
func = scm_variable_ref(func_symbol);
ret=scm_call_4(func,scm_int2num(i),scm_int2num(j),scm_int2num(k),scm_double2num(currentTime));
retValue = scm_num2double(ret,0,"fdtd");
printf("Value from guile is tmp=%d %g\n",tmp,retValue);
}
The break point in one case was after 4000+ calls. I was able to
localize the point of failure to the "scm_call_4" line. Any clue would
be greatly appreciated.
Thanks,
- Anand
