Hi Steve, Please do send me the preprocessed source and if possible also instructions for configuring a MIPS cross-compiler. I haven't been able to reproduce this with either x86_64 or the aarch64 cross-compiler I built yesterday. But I can't reproduce Christophe's failure either with my aarch64-configured glibc, so my version or headers must be different. Thanks!
