misleading message fatal error - cygheap base mismatch detected

["Robert Sandefur" <RSandefur at cam-llc dot com>]

Hi-

I have some legacy FORTRAN code which works fine on ubuntu 64bit. However when I recompiled on cygwin I got the following error:

$ bin/mseval
????? 1 [main] mseval 5468 P:\rlstools\bin\mseval.exe: *** fatal error - cygheap base mismatch detected - 0x61239790/0x6D3D9790.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility and delete all but the most recent version.? The most recent version *should* reside in x:\cygwin\bin, where 'x' is the drive on which you have installed the cygwin distribution.? Rebooting is also suggested if you are unable to find another cygwin DLL.

As it turns out I was allocating too much memory and when I reduce my array sizes everything works fine. I know the message says probably but it might not hurt to suggest that the program is too big to fit in memory
