Bug#954898: libgccjit0: libgccjit segmentation fault
Package: libgccjit0
Version: 10-20200324-1
Severity: important
Dear Maintainer,
I tried to complie GCC JIT's offiical hello world example shown on
https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html
Compilation worked well without any error message, however, when I ran the generated binary, it shows a segmentation fault, gdb output suggests it's caused by libgccjit:
