Bug ID: 90093
Summary: Extended C interop: optional argument incorrectly
identified as PRESENT
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: Bader at lrz dot de
Target Milestone: ---
Created attachment 46166
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46166&action=edit
UNIX archive with test case
The attached test code can be compiled with
gcc -c optional_02_pos.c
gfortran optional_02_pos.f90 optional_02_pos.o
and produces the output
FAIL 2 T T T
The cause of this is that the call of the procedure from C with NULL as
first argument is incorrectly treated.
This appears to be a regression of the most recent fixes for the C descriptor.
