Hi,
I've been busy trying to generate chart definition files using scanin. Testing
the result once I've hit the wrong files on the command line and got a
program error. Usually if the input file does not match the chart I just got
a
"""
../argyll-0.7b8/bin/scanin: Error - Code 0x2, Pattern match wasn't good enough
"""
But in one case the application crashed with a "double free or corruption".
Here's the output gdb gave me. I have not undertaken the venture of building
binaries with debug symbols, or anything else. BTW, it's running on an Ubuntu
Gutsy 32 bit system, using argyll-0.7b8.
Here underneath is the output. For further info ... feel free to ask :)
