Bug ID: 64721
Summary: SIBAGRT turns into SIGSEGV in jit testsuite
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Failures of the CHECK_ macros within jit/harness.h call abort(), which ought to
appear in the logs as a FAIL with SIGABRT.
However, they actually lead to a SIGSEGV.
Program received signal SIGSEGV, Segmentation fault.
