Bug ID: 124287
Summary: tsan tests may sometimes fail due to inadequate
environment
Product: gcc
Version: 15.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: siddhesh at gcc dot gnu.org
Target Milestone: ---
We have seen g++.dg/tsan/pthread_cond_clockwait.C fail with the following
error:
==1531212==WARNING: Program is run with limited virtual address space, which
wouldn't work with ThreadSanitizer.
==1531212==Re-execing with unlimited virtual address space.
==1531212==ERROR: ThreadSanitizer setrlimit() failed 22
FAIL: g++.dg/tsan/pthread_cond_clockwait.C -O0 execution test
which is due to the fact that tsan need to be able to allocate a certain
minimum amount of address space to function. Ideally all tsan tests should
detect this condition during the execution test and report as UNSUPPORTED
instead of FAIL.
