f8fba59804 Replace alloc_struct, free_struct 
Both functions simply call malloc, free.

Remove also unneeded null pointer checks and use calloc where possible.

1cc511188d Added extra Init that takes a memory buffer or a filereader function pointer to enable read of traineddata from memory or foreign file systems. Updated existing readers to use TFile API instead of FILE. This does not yet add big-endian capability to LSTM, but it is very easy from here. 2017-04-27 15:48:23 -07:00

23a7330c85 Fix page range in log message 
The internal range is 0...(n-1), but for users a page range 1...n is
more natural. Showing a range 0...n is wrong because it would imply
n+1 pages.

70fd7cdf0a ccstruct: Fix compiler warning (disable buggy code) 
gcc reports a potential bad array access:

ccstruct/mod128.cpp:98:20: warning:
 array subscript has type 'char' [-Wchar-subscripts]

dir is of type 'char'. Most compilers use signed char by default.
Then the value of dir is in the range -128 ... 127 and cannot be
used to access an array with 256 elements.

Don't fix that but disable the buggy code.
