Bug ID: 119520
Summary: cobol1: internal compiler error: Segmentation fault
(use of field with unknown TYPEDEF)
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: cobol
Assignee: unassigned at gcc dot gnu.org
Reporter: simonsobisch at gnu dot org
Target Milestone: ---
This program uses several typedefs and because of another bug (acknowledged by
James K. Lowden already who might file a bug on that: ">>IF CVAR IS NOT
DEFINED" is always coming back true) the typedef "INT" is not defined.
Therefore the compiler correctly finds at the time when that typedef is used:
01 SOPME-GID USAGE INT VALUE ZERO.
raises
DATA-ITEM 'INT' not found
I _guess_ that the data-item which wanted to use this typedef is in some
strange state afterwards and the internal use of this lead to the following
error:
