Bug ID: 79190
Summary: [7 Regression] ld: (Warning) Unsatisfied symbol
"aligned_alloc"
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: danglin at gcc dot gnu.org
CC: jwakely.gcc at gmail dot com
Target Milestone: ---
Host: hppa*-*-hpux11.00
Target: hppa*-*-hpux11.00
Build: hppa*-*-hpux11.00
HP-UX 11.00 lacks aligned_alloc, posix_memalign, memalign and _aligned_malloc.
This results in aligned_alloc being used as default. As a results, we have
hundreds of g++ and libstdc++ testsuite fails. For example,
spawn -ignore SIGHUP /home/gnu/gcc/objdir/gcc/testsuite/g++/../../xg++
-B/home/gnu/gcc/objdir/gcc/testsuite/g++/../../ cp_compat_main_tst.o

Looking at libstdc++.a, the undefined symbol appears to be in new_opa.o:
