Bug#237126: [arm] ICE when compiling nessus 2.0.10a

[Javier Fernández-Sanguino Peña <jfs@computer.org>]

Package: gcc-3.3
Version: 1:3.3.3-0pre3
Priority: normal

When compiling nessus 2.0.10a in the arm architecture:

(...)
cc -g -Wall -O2  `sh ./cflags`	 -c monitor_dialog.c 
gcc -g -Wall -O2  `sh ./cflags`	 -c backend.c 	
backend.c: In function `backend_empty':
backend.c:566: error: insn does not satisfy its constraints:

make[2]: *** [backend.o] Error 1

Full build log is available at

After talking with the Nessus maintainer it seems this error is "expected" 
when building on arm with optimization. I'm going to upload a new version 
2.0.10a-3 with code that inhibits -O code when building on arm to see how 
the buildd reacts.

Nevertheless, I'm filing this bug since I've seen similar ICE errors 
reported. Since the gcc version used by the buildd you might want to 
contact the buildd managers directly in order to do tests with newer 
gcc-3.3 versions

Thanks
