Description
It's a little bit tricky to reproduce but the loadtxt test occasionally fails (maybe 10-20% of the time). Mostly, it happens in the CI with the combination ubuntu-latest/gcc/12/cmake:
159/324 Test #158: loadtxt ................................***Failed 0.01 sec
At line 171 of file /home/runner/work/stdlib/stdlib/build/src/stdlib_io.f90
Fortran runtime error: Bad value during floating point read
Error termination. Backtrace:

#7 0x55e0c2cc33c7 in MAIN__
#8 0x55e0c2cc345b in main
However, I've also seen it happening with intel and intel-classic:

Expected Behaviour
Test reliably not failing.
Version of stdlib
master
Platform and Architecture
CI: Mostly ubuntu-latest, gcc-12, cmake, but also with other combinations, e.g. ifort

Note the following thread on the Fortran discourse has some similarities to this issues, however not sure they are related.
