Stack overflow weirdness

While tuning some code, the test programme suddenly started producing stack overflows. Reverting the code to a previous version did not revert that behaviour, code that previously produced a well-behaved binary now produced stack overflowing ones. But only with ghc-7.0.1, not with ghc-6.12.3

handleToFd without closing of the file descriptor

Hello I need to get the file descriptor, which is encapsulated inside a handle. handleToFd gets it, but the fd is closed. Is it possible to extract the fd from the handle, without modifying the handle? Greetings, Volker ___ Glasgow-haskell-users
