Re: 1.1.3: mmap() returns unusable memory segments: segm fault


Hi Corinna,

With cygwin's mmap.cc I guess, I cannot map more than 197 MB ?!
Is that correct?

In my application I always call mmap(NULL,size,PROT_RW,...)
here is what I get:
mmap segment[0]: 0x202d0000...0x202dffff = 64 kB
mmap segment[1]: 0x202e0000...0x202effff = 64 kB
mmap segment[2]: 0x202f0000...0x2030ffff = 128 kB
mmap segment[3]: 0x20310000...0x2034ffff = 256 kB
mmap segment[4]: 0x20350000...0x203cffff = 512 kB
mmap segment[5]: 0x209d0000...0x20acffff = 1024 kB
mmap segment[6]: 0x20ad0000...0x20ccffff = 2048 kB
mmap segment[7]: 0x20cd0000...0x210cffff = 4096 kB
mmap segment[8]: 0x210d0000...0x218cffff = 8192 kB
mmap segment[9]: 0x218d0000...0x228cffff = 16384 kB
mmap segment[10]: 0x228d0000...0x248cffff = 32768 kB
mmap segment[11]: 0x248d0000...0x288cffff = 65536 kB
mmap segment[12]: 0x288d0000...0x2c8cffff = 65536 kB

Then, when I try to map another 16384 kB or more, I get
"Permission denied".

I tried cygwin.dll 1.3.4-2 and 1.3.6-6.
Just in case you don't konw or if you want to comment it.

Lothar.
