The following test case is distilled from the LAPACK timing test cases. These used to work on some previous versions of cygwin/g77, but now fail.
The reduced test case is integer n parameter( n = 39*1024*1024 ) ! 38*1024*1024 is OK real a(n) end When compiled with current cygwin g77 (3.3.3) using the command g77 -o labug.exe -O0 labug.f then run I get the error C:\cygwin\usr\local\obj\LAPACK\LAPACK-g77\TIMING\LIN\labug.exe (2324): *** MapViewOfFileEx0x728, in_h 0x728) failed, Win32 error 6 The cases passes for n=38*1024*1024 David NOTICE This e-mail and any attachments are private and confidential and may contain privileged information.
