Subject: [ruby-core:89880] [Ruby trunk Bug#15307] TestJIT#test_{catching_deep_exception, compile_insn_throw, lambda_longjmp} segfaults
Issue #15307 has been updated by vo.x (Vit Ondruch).
It seems that `-fcf-protection` makes the difference. IOW this makes the test (specifically testing with test_lambda_longjmp) fail:
~~~
CFLAGS="-fcf-protection" \
CXXFLAGS="-fcf-protection" \
LDFLAGS="" \
FFLAGS="" \
FCFLAGS="" ./configure
~~~
This is the resulting configuration:
