This was caused by ppmd7 operations calling -rar_br_fillup. This would invoke rar_read_ahead, which would in some -situations invoke archive_read_format_rar_read_header. That would -check the new file name against the old file name, and if they didn't -match up it would free the ppmd7 buffer and allocate a new -one. However, because the ppmd7 decoder wasn't actually done with the -buffer, it would continue to used the freed buffer. Both reads and -writes to the freed region can be observed. - -This is quite tricky to solve: once the buffer has been freed it is -too late, as the ppmd7 decoder functions almost universally assume -success - there's no way for ppmd_read to signal error, nor are there -good ways for functions like Range_Normalise to propagate them. So we -can't detect after the fact that we're in an invalid state - e.g. by -checking rar->cursor, we have to prevent ourselves from ever ending up -there. So, when we are in the dangerous part or rar_read_ahead that -assumes a valid split, we set a flag force read_header to either go -down the path for split files or bail.
