DEAR Sir : GNU
I am writing to you regarding bug report
It resulted based on the last point when having experimented ..the
following...
#include <stdio.h>
#include <values.h>
void subroutine(int n)
{
int buf[n];
fprintf(stderr, "%d (%d)\n", (int)sizeof(buf), (unsigned long)buf);
}
int main( int argc, char **argv)
{
int i, value[] = {2000000, 2500000, 3000000};
for (i=0; i<3; i++) {
fprintf(stderr, "%d: ", value[i]);
subroutine(value[i]);
}
exit(0);
}
① gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
stacksize 8192 kbytes
2000000: 8000000 (-1081748336)
2500000: segmentation fault (core dumped)
② gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)
stacksize 10240 kbytes
2000000: 8000000 (-1081748128)
2500000: 10000000 (-1083748128)
3000000: segmentation fault (core dumped)
It was not bug of gcc but it was a problem of stacksize.
Thanks.
Sincerely yours,
EISUKE HAYASHI
