Hello!
Due to a bug in gcc, the compiler currently segfaults on sh4 with -O2 unless
-fno-guess-branch-probability is passed as well [1]:
during RTL pass: mach
pcrasterutil.cpp: In function 'void castValuesToBooleanRange(void*, size_t,
CSF_CR)':
pcrasterutil.cpp:674:1: internal compiler error: Segmentation fault
674 | }

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-10/README.Bugs> for instructions.
The attached patch for debian/rules works around this problem by passing the
necessary
-fno-guess-branch-probability through DEB_CXXFLAGS_APPEND on sh4 (and sh3):
