--- Comment #1 from Piotr Caban <piotr.caban at gmail.com> ---
This is a valgrind bug. Strtod uses long double during computations.

>From http://www.valgrind.org/docs/manual/manual-core.html:

Valgrind has the following limitations in its implementation of x86/AMD64
floating point relative to IEEE754.

Precision: There is no support for 80 bit arithmetic. Internally, Valgrind
represents all such "long double" numbers in 64 bits, and so there may be some
differences in results. Whether or not this is critical remains to be seen.
Note, the x86/amd64 fldt/fstpt instructions (read/write 80-bit numbers) are
correctly simulated, using conversions to/from 64 bits, so that in-memory
images of 80-bit numbers look correct if anyone wants to see.
