[parisc-linux] strace -f caused kernel fault

[Matthew Wilcox]

just trying to track down a problem with libc, I did:

$ strace -f 2>strace.out make check
make -r PARALLELMFLAGS="" CVSOPTS="" -C ../libc objdir=`pwd` check

and then on console, i got:

Dumping Stack from 0000000035efc000 to 0000000035efcbc0:                        

[stack dump snipped]
