valgrind spews a lot of these: strchr (mac_replace_strmem.c:113) nsINIParser::FindKey(char*, char*, char*, int*) (nsINIParser.cpp:245) nsINIParser::GetString(char*, char*, char*, int*) (nsINIParser.cpp:108) nsINIParser::GetStringAlloc(char*, char*, char**, int*) (nsINIParser.cpp:122) Address 0x58EE18A is 0 bytes after a block of size 3238 alloc'd malloc (vg_replace_malloc.c:160) nsINIParser::nsINIParser(char*) (nsINIParser.cpp:59) nsXIContext::LoadResources() (nsXIContext.cpp:137) nsXInstaller::ParseConfig() (nsXInstaller.cpp:95) the file is read into a buffer just big enough for its contents. There is no room for NULL termination.
