Hi,
Saw this in vs2010 when I tried to load an .flt file freshly made in creator
but with nothing in it. You get a string index out of range exception in
PaletterRecords.cpp, line 73 where it does
uint32 paletteSize = in.readUInt32();
// Entries in vertex pool found by offset from start of this record.
const int RECORD_HEADER_SIZE = 4;
const int OFFSET = RECORD_HEADER_SIZE+sizeof(paletteSize);
std::string buffer(paletteSize,'\0');
in.read(&buffer[OFFSET], paletteSize-OFFSET);
The problem is that for an empty vertex palette, OFFSET equals paletteSize, so
OFFSET is past the end of buffer. This code normally doesn't have a problem
because it's reading 0 bytes into this location anyway, but iterator debugging
catches the out of range index.
A simple if (OFFSET < buffer.size()) fixes the problem. I attached an amended
file with the fix, plus a test model that reproduces the problem.
Hope that's helpful -- thanks for all the wonderful work on OSG.
Nathan
