Priority: Medium

Class: Bug

Severity: Serious

Number: 12782

Release: 6.0.68434

Confidential: No

Status: Closed

Responsible: manus_eiffel

Synopsis: Changing generic class to non-generic and recompiling crashes in degree 1

Description

Changing a particular class from generic to non-generic and recompiling
causes the compiler to crash in degree 1.  This is an incrementality bug, since
the new set of classes compiles fine from scratch.  There might already be an
eweasel test for this but I don't follow eweasel as much as I used to.

To Reproduce

Compile with attached classes, using file test_old.e, test1_old.e and test2_old.e.
Then recompile with contents of these classes replaced by test_new.e,
test1_new.e and test2_new.e, respectively.  Compiler crashes in degree 1
with attached trace.
