gcc 4.4.0 error at postreload.c:396

[Bernd Roesch <nospamname at gmx dot de>]

Hi,

I search gcc ML and find this.

http://gcc.gnu.org/ml/gcc/2009-05/msg00413.html

but here i have source with no 64 bit CPU.
is the fix now in and should i test current gcc4.4 ?

I also like to know if there is possible to build a gcc with better error
messages ?
It show as error place last bracket of the function.

Get a report of GCC 4.4.0 internal compiler error.happen on the last
bracket of the function.see --> mark
he report that GCC 4.3.2 work ok with same source.

the source is in ffmpeg package and gcc4.4.0 (release)run on cygwin.
A preprocessed source i do not have, hope this can help and somebody can
tell me what problem can be or how get more precise info about problem.

Here is output:

GCC 4.3.2 don't have this error - compiles "mpegvideo.c" file without
