>Description:
Preprocessing altivec code it just consumes all the memory and then dies reporting:                                                                                
cpp0: Cannot allocate 262144112 bytes after allocating 7222368 bytes
the system has 512mb ram and 800mb swap
The file is a cut down motion_comp_altivec.c from libmpeg2, that I just used to restrict the faulting part (the rest is compiling ok)
>How-To-Repeat:
that is enough
gcc -c -Os -maltivec -mabi=altivec -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I. -I../libvo -I..   -DMPG12PLAY -o motion_comp_altivec.2.o motion_comp_altivec.2.c -E
                                                                                
that is the result
