This works too: # ocamlc -o x.cmo t.ml My guess: when you say "ocamlc -o t.cmo t.ml", the compiler first compiles t.ml to t.cmo, then tries to link the t.cmo object file to produce an executable named t.cmo. At some point, it opens t.cmo for writing (thus erasing it), then tries to copy data from t.cmo to t.cmo, which fails. I think we need a better error message. In the meantime, the workaround is obvious: don't do that. Also, I have no idea how it could work in 3.12.1... |

Improved error message to avoid clashes: r12901 |

r 12901 (in trunk) fixes this. |
