Hi,
I am trying to run a simulation in C on my Win2K-machine (the simulation
runs perfectly on a Linux-PC)
The problem seems to be that with certain parameters, I get some huge
3-dimensional arrays that require like 20-40MB RAM.
When I have a size of about 22MB the simulation works fine, when I
increase the array size by ~1.33 (should then still be below but close
to 32MB) it doesn't start with the error message
C:\cygwin\home\clevorn\wlan15\Main.exe: *** Couldn't reserve space for
cygwin's heap (0x20030000) in child, cygheap, Win32 error 487
I tried two solutions posted in this mailing list for similiar problems:
first:
the "gcc -Wl,--heap,50000000,--stack,--50000000 ..." solution
here the simulation fails at small array sizes too.
second:
the "gcc -mno-cygwin ..." solution
here the program does start, but the only thing that happens is, if you
look in the task manager, the process slowly "collects" memory for about
90 seconds until it recaches 32MB (33xxxkB) and than the process crashes
with the windows message " the exception unknown software exception
(0xc00000fd) occured in the application at location 0x6104b9ef". During
that time the VM Size increases with the same rate, only it start at
values like 4xxMB or 6xxMB, depending on the array size (I have 1 GB RAM
so the pure size of these value isn't the real problem).
I think that the size of slightly below or even above 32MB is the cause
of the problem. Is there a general problem with cygwin and running
programs that require this amount of memory. Is there a way around this
problem.
Thanks for yor help!
Regards,
Thorsten
