Bug #: 13331
Summary: (cpychecker) Segfault in
gdb/python/py-function.c:convert_values_to_python
under low memory conditions
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: python
AssignedTo: unassigned@sourceware.org
ReportedBy: dmalcolm@redhat.com
Classification: Unclassified
Created attachment 6025
--> http://sourceware.org/bugzilla/attachment.cgi?id=6025
HTML report showing the execution paths that can crash
convert_values_to_python doesn't check the return value from PyTuple_New, which
can return NULL under low memory conditions.
If it returns NULL and argc > 0 then there are two different segfaults
possible; see attached HTML.
