Package: systemtap-sdt-dev
Version: 4.6-1
Severity: normal
dtrace generates .c code in a predictable temporary file which makes it
susceptible to crashes. I've seen this happen in practice when rebuilding
libvirt/focal on a system with 48 cores. The race window is wide enough that
the crash is nearly 100% reproducible.
I submitted a patch upstream that has now been accepted:
https://sourceware.org/git/?p=systemtap.git;a=commit;h=0de9020c970bceda73e32bbd169c12e7579f21ec
Can we get that fix applied to Debian?
