Bug Description

When compiling libvpx, I get the following compile error:

    [CC] vp9/encoder/vp9_speed_features.c.o
vp9/encoder/vp9_speed_features.c: In function ‘vp9_set_speed_features’:
vp9/encoder/vp9_speed_features.c:327:6: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.launchpad.net/gcc-linaro> for instructions.
make[1]: *** [vp9/encoder/vp9_speed_features.c.o] Error 1
make: *** [.DEFAULT] Error 2

I read a similar looking bug report and added the following to .config params: --extra-cflags="-fno-schedule-insns -fno-schedule-insns" but it still failed

Please advise

Thanks

I cannot reproduce this.

Please run the failing command line with -save-temps, and send the preprocessed source (the .i or .ii file), along with the command line used to reproduce the crash
