gcc version 3.4.5 (mingw special)
The following testcase shows the stack grows every time an exception get
handled
until the program runs out of stack and crashs.
----------------------------------------
#include <stdio.h>
int main()
{
while(1)
{
try {
int n = 8*1024;
int p[n];
fprintf(stderr, "p=%p\n", p);
throw 1;
}catch(...) {
}
}
}
