Summary0015589: Crash when fetching larger data file with External Data on Windows
DescriptionWe have been using the external data mechanism with great success for several months.

Recently, an 800Mb file was added to our test data and on Windows cmake crashes with a std::bad_alloc during a curl callback. The download works fine on Linux and Mac OS X.

The full stack trace from Visual Studio is:

The insert line in cmFileCommand.cxx::cmFileCommandCurlDebugCallback causes a memory allocation error.
Steps To ReproduceI have placed an isolated test project at https://github.com/martyngigg/external-data-win32-crash [^] that reproduces the error using one of our large files.

Running cmake on the project and then building with

msbuild ExternalDataTest.sln

will reproduce the issue.

 This should fix it:

 cmFileCommand: Do not log raw protocol data from curl
