--- Comment #48 from John David Anglin <danglin at gcc dot gnu.org> ---
There is an endian issue in the call to ___pthread_cond_timedwait64
which breaks v18 on hppa:
(gdb) r
The program being debugged has been started already.
Start it from the beginning? (y or n) y
Starting program:

debugging will not be available.
