Description Mark Wielaard 2018-11-23 15:32:25 UTC
On ppc64le gcc8 generates inlined code for str[n]cmp that valgrind memcheck
cannot proof correct. gcc9/trunk generates slightly different code for the
inlined strncmp code that valgrind memcheck can proof correct with some
patches. glibc uses inlined str[n]cmp in various functions.

Once the gcc patch has been backported (#1652927) glibc should be rebuild with the new gcc to solve the valgrind bug (#1652926).

Comment 1 Mark Wielaard 2018-12-20 21:42:55 UTC
gcc-8.2.1-6 has landed in f28 and f29.
valgrind-3.14.0-7 has been pushed to fedora 28 and fedora 29 testing.
It would be great if glibc could be rebuild against the new gcc now for f28 and f29.
