In case this helps, I have attached the assembly diffs from...
gcc-4 -O1 -m32 -g --save-temps complex-sign-add_red_1.c
for the 20090908 compiler (before the VTA merge) and for the 20091118 compiler.

Note that the dsymutil failure for the test in comment 11 disappears in 64 bit

The original code in the test suite gives:

Dominique,
Can code in comment 11 be converted into a test case that can be run
through dsymutil without requiring FSF gcc to be installed? If so, please open
a radar report with that information.
