Bug #: 15162
Summary: eh_frame table too big, may kernel panic
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
AssignedTo: systemtap@sourceware.org
ReportedBy: jistone@redhat.com
Classification: Unclassified
Reported here: http://sourceware.org/ml/systemtap/2013-q1/msg00144.html
We have a limit of MAX_UNWIND_TABLE_SIZE for each of the eh/dwarf unwind
tables, and binaries which exceed this are skipped. However, it appears that
the skipping is not quite complete, and can sometimes lead to a kernel panic.
