+===========================GNAT BUG DETECTED==============================+
| 4.4.5 (x86_64-pc-linux-gnu) in tree_low_cst, at tree.c:5018 |
| Error detected at showbug.adb:29:28 ..... etc
Problem appears to be due to an indetermined length array (MAP1) held within a
nested variant record structure. Adding additional components to the EnDep_T
record (ie replacing B=> null; with B=> Dum: Integer) or re-ordering the arrays
MAP1 and MAP2, code compiles.
Code compiles on older version: gcc 4.3.2 and GNAT 4.3.2
