[Bug middle-end/36593] New: [4.4 Regression]: gfortran.dg/default_format_1.f90, 22_locale/num_get/get/char/2.cc

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With r136685, these tests passed.  They are known to fail since r136695.
Both seem to be related to formatting of floating point numbers; possibly a
miscompilation of newlib.  None of the libraries or front-ends had related
changes in the svn range.

The gfortran test fails at execution at all the torture options, calling abort
for one of the subtests.  The libstdc++ test fails with (copypasted):
assertion "d == d1" failed: file
"/tmp/hpautotest-gcc1/gcc/libstdc++-v3/testsuite/22_locale/num_get/get/char/2.cc",
line 101, function: void test02()^M
program stopped with signal 6.^M

I'll add an investigation from diffed disassembled executables and simulator
traces.
