[cfe-dev] Memory issue on Linux

[Belcourt, Kenneth]

Hi,

I apologize if this is the wrong list.  I've been running Boost trunk regression tests with trunk clang and wanted to point out this test on Linux consumes rather a lot of memory, and continues to consume memory if I let it run.  I've pasted the compile line in case that helps.  I'm unable to build clang trunk optimized on Linux, not sure why and don't know whether that would dramatically affect the compiler memory footprint anyways.  I haven't checked to see if the problem exists on the Mac.
