Bug ID: 85340
Summary: allocate_deferred_char_scalar_1.f03 dereferences null
pointer
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: zeccav at gmail dot com
Target Milestone: ---
Testsuite program allocate_deferred_char_scalar_1.f03 at lines 68 and 69
dereferences pointer str4 which was nullified at line 66.
Same at lines 39 and 40.
This is wrong and should be detected by -fcheck=pointer option.
Putting "if(!s1) runtime_error ("Dereferencing null pointer");" before line 90
of libgfortran/intrinsics/string_intrinsics_inc.c detects the bugs at lines 68
and 39.
On trunk 259205.
