--- Comment #6 from Jonathan Ben-Avraham <yba at tkos dot co.il> --- (In reply to Richard Earnshaw from comment #1) > The gcc developers do not use crosstool, so providing us with a config for > it is of no help. Furthermore, un-preprocessed source means we are unlikely > to be able to reproduce the exact conditions leading up to the failure you > see. > > What we do need are: > > 1) The output of "gcc -v", showing how the compiler was actually configured. > 2) *Pre-processed* source that we can feed into our own builds of the > compiler to try to reproduce the problem jonathana@orcam81:~/pub/gcc/bugs$ /homes/jonathana/pub/mxs/tc/2015092100/arm-mxs-linux-gnueabihf/bin/arm-mxs-linux-gnueabihf-gcc -v Using built-in specs.
