RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #1983696 +++

This code in js/xpconnect/src/XPCJSContext.cpp fails to build with glibc 2.34:

static constexpr size_t kWatchdogStackSize =
    PTHREAD_STACK_MIN < 32 * 1024 ? 32 * 1024 : PTHREAD_STACK_MIN;

I'm not sure to what extent this optimization is important, given that the kernel will not use memory for unused areas of the stack. The use of PTHREAD_STACK_MIN is dubious anyway because the constant only means that pthread_attr_setstack will not fail. It doesn't say that the thread stack is useful for running any application code.

PTHREAD_STACK_MIN patch

Eike, can you please get this in when you will be doing the next ESR 78.13 update in Stream? Also do the same for Thunderbird (see bug 1984794). Looking at the upstream bug it will probably be resolved upstream as well and will be part of ESR 91. If not then we have to backport it there when we will finish the rebase.

I will take this as I have to do a Firefox/Thunderbird build now and without this change it's not possible to build Firefox/Thunderbird.
