This bug can be reproduced using the standard gcc 4.6.3 packages that is part
of the Debian wheezy armhf port.  The command line to trigger the bug is:

 gcc -DPERL_CORE -c -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -D_FORTIFY_SOURCE=2 -g
-O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security
-Werror=format-security -fno-strict-aliasing -pipe -I/usr/local/include
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64   -O2 -g -Wall   -W -Wextra
-Wdeclaration-after-statement -Wendif-labels -Wc++-compat -Wwrite-strings -marm
-march=armv6 -mfpu=vfp -o cccPDUUP.o cccPDUUP.

The regular Debian wheezy gcc is configured with the following options:

Configured with: ../src/configure -v --with-pkgversion='Debian 4.6.3-1'
