[Bug fortran/42783] New: [4.5 Regression] Bogus Array bounds violation with optional array argument

[anlauf at gmx dot de]

Hi,

when compiled with -fbounds-check, the attached code fails at runtime
with the following error:

At line 8 of file gfcbug99.f90
Fortran runtime error: Actual string length does not match the declared one for
dummy argument 'mnem_list' (0/8)

No problem with 4.4.0 or earlier.
