Hi all.
libc = libc6 v.2.2.5-3
libstdc++ = v 3.0.4-6
(debian packaging numbers)
The subject should be self explanatory. Could this have anything to do
with libstdc++, or is that a red herring.
I also have equally reproducible results on valarray destruction and
subsequent calls to libc:free, but I figured that those had a greater
likelihood of being the fault of libstdc++ or me and not glibc. Now I'm
not so sure -- the stack trace below looks pretty incriminating to me.
Other unusual variants: I'm linking against libf2c, libblas, and
liblapack -- don't know much about fortran, but could that have some bad
interaction with libc?
I'd be happy to tar up my code if anyone is interested.
Cheers,
Craig

PS is it usual for malloc to call itself recursively like this?
