segfault in the internals of malloc after emacs fdopen()s for the 6th time

[alexbl]

I'm trying to get emacs running on haiku, after two days I got it to compile, but when trying to bootstrap emacs, I receive this backtrace after emacs has opened 5 other files using the same code path.

I'm running alpha1, but I also tried against a hrev33601 x86gcc4hybrid nightly. I'm using gcc4 to compile emacs.
