Bug #: 15144
Summary: occasional (40%) stapdyn spin/hang during sdt.exp
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dyninst
AssignedTo: systemtap@sourceware.org
ReportedBy: fche@redhat.com
Classification: Unclassified
With git systemtap, rawhide 3.8.0-rc7 kernel, dyninst 8.0,
# make installcheck RUNTESTFLAGS=sdt.exp
About half the time, we get a stapdyn hang/loop in the test:
executing: stap --runtime=dyninst -w
/home/fche/Private/DEVEL/DEVEL-systemtap/git/systemtap3/testsuite/systemtap.base/sdt.stp
sdt.c.exe.2 -c ./sdt.c.exe.2
... top shows one of the stapdyn threads spinning with 100% cpu
