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!
