Comment author: @alainfrisch I think this is a duplicate of #5205. Now we have two patches :-) |

Comment author: @lefessan You are right, I didn't understand it was the same issue, but looking at the patches, we are fixing the same problem with two different patches ;-) |

Comment author: @xavierleroy Implemented in SVN trunk, along the lines of Fabrice's patch but (for the time being) without the inlining of locally-let-bound functions. |

Bug description
Pattern-matching generate aliases of variables during its
compilation. Such aliases are evaluated lazily when they are used only
once. This optimization is performed even if they are used in an
abstraction, in which case they might make a bigger datastructure
escape from its scope, and lead to an important memory leak.
The following patch fixes this behavior by preventing the substitution when
aliases are used in abstractions and in loops.
