I reported this bug against a SPARC system at #42753, but as this is a
different version of gcc, on a different operating system with a different
processor, I thought it wise to create another ticket.
The hardware is a Sun Ultra 27, with a 3.33 GHz Xeon processor.
The attached code builds and runs as expected using the Sun Studio 12.1
compiler.
drkir...@hawk:~$ /opt/sunstudio12.1/bin/cc -V simple_complex.c
cc: Sun C 5.10 SunOS_i386 2009/06/03

ld: Software Generation Utilities - Solaris Link Editors: 5.11-1.1652
drkir...@hawk:~$ ./a.out
CYTHON_CCOMPLEX 1
However, it fails with gcc 4.3.4
