I'm having trouble converting some netcdf (version 3) files to Kea files using the GDAL C# bindings.
The problem is some form of memory leak caused by the netCDF code (from what I can establish through various tests). There are two issues: 1) A memory leak in this call (which I noticed, but can work around as I am only dealing with a small number of subdatasets) a. dsNetCDF = OSGeo.GDAL.Gdal.Open(strNetCDF_DSN, OSGeo.GDAL.Access.GA_ReadOnly); 2) A memory issue/leak pointer assignment causing a crash that I cannot trace the error reports as: Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'O:\Projects\KEA_ReadWrite\bin\x64\Debug\KEA_ReadWrite.vshost.exe'. Additional Information: The runtime has encountered a fatal error. The address of the error was at 0xebc85654, on thread 0x16ec. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack. The error is consistent in nature but happens inconsistently in the code (between 1800 and 4000 bands) - here from another run: Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'O:\Projects\KEA_ReadWrite\bin\x64\Debug\KEA_ReadWrite.vshost.exe'. Additional Information: The runtime has encountered a fatal error. The address of the error was at 0xebc85654, on thread 0x199c. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack. The error MAY be occurring more often only on lines handling string functions (?)

Input files have between 365 and 8000 bands but not large spatially (260*243). ________________________________ Please consider the environment before printing this email Warning: This electronic message together with any attachments is confidential.
