Hi, When compiling plbuf.c, MS Visual Studio 9 2008 issues the following warning
plbuf.c(1159) : warning C4700: uninitialized local variable 'new_state' used. This occurs in - void plbuf_restore(PLStream *pls, void *state) { struct _state *new_state; (plbuf.c line 1154) #ifdef BUFFERED_FILE pls->plbufFile = new_state->save_file; #else pls->plbuf_buffer = new_state->plbuf_buffer; (plbuf.c line 1159) pls->plbuf_buffer_size = new_state->plbuf_buffer_size; pls->plbuf_top = new_state->plbuf_top; pls->plbuf_readpos = new_state->plbuf_readpos; #endif /* cmap 0 */ pls->cmap0 = new_state->color_map[0].cmap; pls->icol0 = new_state->color_map[0].icol; pls->ncol0 = new_state->color_map[0].ncol; /* cmap 1 */ pls->cmap1 = new_state->color_map[1].cmap; pls->icol1 = new_state->color_map[1].icol; pls->ncol1 = new_state->color_map[1].ncol; } I don't have a test case but inspecting the code suggests that if plbuf_restore is called this would give rise to errors in the color maps and further memory corruption. new_state should be initialised in line 1154 as follows struct _state *new_state = (struct _state *)state; Note plbuf_restore is called by plbuf_switch.
