Description Peter Klotz 2002-01-30 20:04:50 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
gcc 3.1-0.10 was able to compile MICO 2.3.6 but gcc 3.1-0.18 cannot. The 
(virtual inheritance) bug that crashed the idl compiler in the gcc 3.0.x 
series has GNATS #3145. It should have been fixed in 3.1.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Get mico-2.3.6.tar.gz
2.Remove all occurrences of -Werror in the configure script
3.Remove ios::noreplace from idl/codegen-c++.cc in lines 220/221
4.Perform configure
5.Perform make	

Actual Results:  The just made idl compiler crashes

make[2]: Entering directory `/root/development/mico/mico/coss/naming'
/root/development/mico/mico/./idl/idl --c++-skel --name CosNaming \
make[2]: *** [CosNaming.cc] Segmentation fault
make[2]: Leaving directory `/root/development/mico/mico/coss/naming'
make[1]: *** [sublib] Error 1
make[1]: Leaving directory `/root/development/mico/mico/coss'

Expected Results:  It should compile. It works under gcc 2.96 and gcc 3.1-
0.10. It never worked under gcc 3.0.x (see above, GNATS bug #3145).
