This is probably a lib problem, but I haven't had anything like it before...
any ideas?
I am using the default 2.0.30 (and pre-10 doesn't fix this), and when
I try and 'make dep' things go haywire:
gcc -I/usr/src/linux/include -O2 -fomit-frame-pointer -o scripts/mkdep scripts/mkdep.c
make[1]: Entering directory `/usr/src/linux/arch/i386/boot'
make[1]: Nothing to be done for `dep'.
make[1]: Leaving directory `/usr/src/linux/arch/i386/boot'
scripts/mkdep init/*.c > .tmpdepend
scripts/mkdep `find /usr/src/linux/include/asm /usr/src/linux/include/linux /usr/src/linux/include/scsi /usr/src/linux/include/net -follow -name \*.h ! -name modversions.h -print` > .hdepend
make: *** [dep-files] Error 139
running the command directly:
newt:/usr/src/linux # scripts/mkdep `find /usr/src/linux/include/asm /usr/src/linux/include/linux /usr/src/linux/include/scsi /usr/src/linux/include/net -follow -name \*.h ! -name modversions.h -print` > .hdepend

an strace shows this:

So I tried to compile mkdep with '-g' and found that doing
gcc -I/usr/src/linux/include -O2 -o scripts/mkdep scripts/mkdep.c
instead of
gcc -I/usr/src/linux/include -O2 -fomit-frame-pointer -o scripts/mkdep scripts/mkdep.c
Works fine.

Any ideas?
The only major thing I have done recently is install glibc, and this isn't
linked with it...
