<div dir="ltr">I agree that this is unfortunate behavior of Windows. Ian Taylor and I did some tests of speed and memory usage between 32-bit and 64-bit compilers and were also puzzled as to why Windows implements long ints as 32-bit. I'm not sure if it is helpful, but a summary of our investigations is here:<div>

Following up on what Arni mentioned about 32-bit and 64-bit compilations, I agree and have set up Visual Studio to compile 32- or 64-bit ADMB programs at my will. Ian Taylor and I set this up to provide 32- and 64-bit Windows versions of Stock Synthesis.</div>

I think the problem is that a long int in windows is
only 32 bytes.<br>
I compiled this in <br>
<br>
gcc -m64<br>
<br>
on linux<br>
<br>
#include <stdio.h><br>
main()<br>
{<br>
int nbits=sizeof(char*);<br>
if (nbits==4)<br>
printf("this is 32 bytes\n");<br>
else if (nbits==8)<br>
printf("this is 64 bytes\n");<br>
else<br>
printf("this can't happen");<br>
<br>
nbits=sizeof(long int);<br>
if (nbits==4)<br>
printf("this is 32 bytes\n");<br>
else if (nbits==8)<br>
printf("this is 64 bytes\n");<br>
else<br>
printf("this can't happen");<br>
<br>
nbits=sizeof(int);<br>
if (nbits==4)<br>
printf("this is 32 bytes\n");<br>
else if (nbits==8)<br>
printf("this is 64 bytes\n");<br>
else<br>
printf("this can't happen");<br>
<br>
}<br>
<br>
on linux I get output<br>
<br>
this is 64 bytes<br>
this is 64 bytes<br>
this is 32 bytes<br>
<br>
using the windows cross compiler I get<br>
<br>
<br>
this is 64 bytes<br>
this is 32 bytes<br>
this is 32 bytes<br>
<br>
so a long int is 32 bytes in the 64 bit version.
Strange eh?<br>

<div dir="ltr">So I installed the 64 bit version of
admb 10.1 and gcc 4.5.2 and the problem persists.
What versions are you using and what type of
machine? I'm running win7 on an 64 bit machine
with 8gb ram. This will be difficult to work this
out if you can't replicate on your machine. What
quantity did you run for -gh? -gh 6 worked for me
but -gh 7 or higher did not. Can you try a higher
-gh value to see if you can get it to fail?
