Bug ID: 89531
Summary: Possible memory corruption in the gfortran front-end
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: GC
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Target: powerpc-*-linux-gnu*

Testcase
gfortran-9.0.0-alpha20190224 snapshot (r269177) ICEs when compiling the
attached testcase extracted from NAS Parallel Benchmarks 3.3.1:
% powerpc-e300c3-linux-gnu-gfortran-9.0.0-alpha20190224 -m32 -O3
-fno-predictive-commoning -fno-tree-scev-cprop -g --param ggc-min-expand=0
--param ggc-min-heapsize=0 --param loop-interchange-stride-ratio=0 --param
max-completely-peeled-insns=3 -c ym32njaj.f
I don't know whether this ICE is target-specific, as I don't have gfortran for
other targets for now.
This seems to be a GC-related error. The compiler crashes in different places,
depending on exact set of the command line arguments and source code included
in the reduced testcase.
