Re: [Gpstk-devel] Malloc error on 2.3

[Bryan P. <bpa...@ar...>]

Hello Sam,

Quick question, what platform are you building on? First glance tells me 
Mac OS X.  Also, can you provide me additional information on your dev 
environment? I like to try to replicate reported issues, and I have yet 
to see this error myself when testing across the supported platforms.

Thanks and We appreciate your interest in the GPS Toolkit,
