[Bug c++/29809] New: Segmentation fault with 4.1.1 and 4.1-20061110

[chris_clayton at f1internet dot com]

I get a segmentation fault with both stock gcc 4.1.1 and the 20061110 4.1.2
snapshot, when trying to build avifile-0.7.45. The error message is:

[Bug middle-end/28116] [4.1 Regression] ICE when building konverter with gcc-4.1 with -O3 [RSO]

I'm the reporter of 29809, which is a duplicate of this bug. I'm not familiar
with the workflow here, so do I simply wait for 4.1.2 or is there likely to be
patch to test before 4.1.2 is released? Is the patch at comment 4 of bug 29809
worth testing - the author seemed to think it was too simple to be true :)?

Thanks

OK, I've updated to the 20061124 snapshot. Without the patch at PR29809, I get
the ICE building avifile-0.7.45 and konverter-0.92-beta1. With the patch, both
builds complete. From my, admittedly minimal, testing, konverter seems to be
working OK. Unfortunately, I don't have the hardware to test the sample
application from the avifile package.

Hope this helps.
