[Bug target/38553] New: [4.3 Regression] Segfault in ggc_set_mark with -maltivec

[tbm at cyrius dot com]

[ forwarded from http://bugs.debian.org/508576 ]

Michael Buesch reported the following segfault with gcc 4.3 on powerpc
with -maltivec.  I confirmed that the bug is still present in 4.3 from SVN
and that it's not present on the trunk.

./xgcc -B. -maltivec --param ggc-min-expand=0 --param ggc-min-heapsize=0 -O3  
-c ~/ad_imaadpcm.i
libmpcodecs/ad_imaadpcm.c: In function 'ms_ima_adpcm_decode_block':
libmpcodecs/ad_imaadpcm.c:273: internal compiler error: Segmentation fault
Please submit a full bug report,
