Summary: In Fedora 30 ps hangs using address sanitizer
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
I'm using Fedora 30 in a docker container running on a Ubuntu 16.04 or 18.04
host. The following command hangs:
LD_PRELOAD=/lib64/libasan.so.5.0.0 ps
The same commands works using Fedora 29.
If I take off the LD_PRELOAD, then the command completes successfully.
An strace always shows it in the following:
futex(0x7f19408a0be8, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 2, NULL,
FUTEX_BITSET_MATCH_ANY
