pr: status ready
…reading and writing same buffer). Fixed: sscanf(buf, "%*127s %127s", matName); Breaking down the format: - %*127s - The * is the assignment suppression modifier. It means "read up to 127 chars but discard them (don't store)". This skips the first word (like "newmtl") - %127s - Read the second word (the material name), limited to 127 chars, store in matName So if buf contains "newmtl MyMaterial\n": - %*127s reads and discards "newmtl" - %127s reads "MyMaterial" into matName The 127 limit prevents buffer overflow since matName is 128 bytes (127 chars + null terminator).

Different overflows risk were not checked,
and one array access is a bug (in BaseContactMapper)
