Re: [ft-devel] FT_New_Memory_Face crashes

Also note, that I have verified that my 'LoadFile' function correctly reads in the input TTF file. I have tested this by writing out the bytes that this function reads in, to a different file, and then comparing the original TTF file with the output. The result is that the two are identical.

I apologize, I made a copy\paste error when providing the sample, I have corrected it below as they are in fact the same buffers in the code I'm running. 

Unfortunately I cannot provide a complete standalone sample as I am working in the Android NDK.

In the code sample, FT_NEW_MEMORY_Face() is passed a different buffer from the one created by LoadFile().

I have loaded an "arial.ttf" file (taken from my /Windows/Fonts folder) into memory, however passing this into FT_New_Memory_Face crashes (I have also tried other ttf files, and this function still crashes). Any clues as to what I might be doing wrong? Note that I am using Freetype with the Android NDK, so it is difficult to debug, however I find that eventually, the crash occurs within:

FT_New_Memory_Face -> FT_Open_Face -> FT_Stream_ReadLong -> crashes at:

if ( p )

{

       result = FT_NEXT_LONG( p ); //crashes here, in file ftstream.c, method FT_Stream_ReadLong

}

And below is my code:

unsigned char *fontBuffer = LoadFile("arial.ttf");

zip_uint64_t fSize = GetFileSize("arial.ttf"); // I checked this, and it returns the correct size

FT_Library  library;

FT_Face     face; 

int error = FT_Init_FreeType( &library ); // I checked this, this step succeeds

if( error != 0 )

    printf("FT_Init_FreeType failed");

error = FT_New_Memory_Face( library,

                            (FT_Byte*)fontBuffer,

                            fSize,                  

                            0,                      

                            &face );
