Hm yes, “--disable-libsanitizer” is rather ominous. I guess the mipsel GCC package has been built without ASan support. Surprising that it fails so messily (the front end seems to think -fsanitize=address is an accepted command line option), but libasan does indeed seem not available on mipsel [0]. The other option I suggested was Valgrind, but if you can’t run apt-file you probably can’t install Valgrind either. If anyone spectating has ideas, please chime in.
