csv-driver: Mismatched free() / delete / delete [ ]

[SpencerFleming]

So, I was working on this as a part of #136, but it's causing me enough trouble that I want to document it as its own issue and get some help with it if I can.

Essentially, despite me getting a csv file with data in it, csv-driver is exiting with code 1. Valgrind tells me the following:

4535 ==36357== Mismatched free() / delete / delete []
4536 ==36357== at 0x4C2AFF8: free (vg_replace_malloc.c:540)
4537 ==36357== by 0x40ABCF: FlightLineData::calc_xyz_activation(std::vector<Peak*, std::allocato r<Peak*> >) (FlightLineData.cpp:379)
4538 ==36357== by 0x40DD53: LidarDriver::fit_data_csv(FlightLineData&, std::vector<std::string, std::allocatorstd::string* >&, csv_CmdLine&) (LidarDriver.cpp:175)

4540 ==36357== Address 0xf0d8360 is 0 bytes inside a block of size 128 alloc'd

4543 ==36357== by 0x413EAF: GaussianFitter::find_peaks(std::vector<Peak, std::allocator<Peak*> >, std::vector<int, std::allocator >, std::vector<int, std::allocator >, unsigned l ong) (GaussianFitter.cpp:365)
4544 ==36357== by 0x40DCB0: LidarDriver::fit_data_csv(FlightLineData&, std::vector<std::string, std::allocatorstd::string* >&, csv_CmdLine&) (LidarDriver.cpp:167)
4545 ==36357== by 0x4059DA: main (pls_to_csv.cpp:46)

fit_data_csv is similar to fit_data, except that instead of putting peaks into a LidarVolume object, it just runs to_string on them and then deletes them. That said, this distinction only occurs once calc_xyz_activation has already been called, so I'm not sure why that would even affect calc_xyz except that perhaps some artifact is being left in the peak vector between iterations, despite my deleting of every peak followed by a clear statement.

Interesting news: I have found that the error in my first comment (mismatched free) is actually a nonfatal error for geotiff-driver. I'll have to do more research with this in mind when I get around do it!
