Subject: 1.1.3: mmap() returns unusable memory segments: segm fault
Date: Mon, 05 Nov 2001 12:08:00 -0000 [thread overview]

Hi,
I run Cygwin 133 on NT4.0SP6 (output of cygcheck -s
is attached). mmap() doesn't work even for a very
simple case. Try:
#include <stdio.h>
#include <sys/mman.h>
int main() {
char* core;
core = mmap(NULL,0x10000,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0);
if (core == MAP_FAILED) goto err;
printf("mmap %p\n", core);
*core = 'A'; /* ok */
core = mmap(NULL,0x20000,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANON,-1,0);
if (core == MAP_FAILED) goto err;
printf("mmap %p\n", core);
*core = 'A'; /* Segmentation fault */
return 0;
err:
perror("mmap");
return 1;
}
------------------------- end of test program -----------------
Same, if I use MA_SHARED. Any Help?
When I run this, I get:
mmap 0x1a230000
mmap 0x1a240000
0 [main] a 126 open_stackdumpfile: Dumping stack trace to a.exe.stackdump Segmentation fault (core dumped)
Lothar.
