tool_parsecfg.c:223:30: runtime error: load of value 9, which is not a valid value for type '_Bool'

[geeknik]

I did this

Compiled with UBSan, ASan and afl-clang-fast.

UBSAN_OPTIONS=print_stacktrace=1:halt_on_error=1 ~/curl/src/curl -K test029 file:///dev/shm/test.png

Note: /dev/shm/test.png does not exist.

I did not expect the following
