crash is really at assembly level. The incriminated line is the first of
these three:
base = try_dir (getenv ("TMPDIR"), base);
base = try_dir (getenv ("TMP"), base);
base = try_dir (getenv ("TEMP"), base);
but... Why?!
I forgot to add -O0 to the debug CFLAGS. Now building the toolchain with:
export CFLAGS="-g -O0 -fno-inline"
export LDFLAGS=-g
