Had to McGyver this, into
cd ./libtest
run debug ../../src/curl --output ../log/curl9.out --include --trace-ascii
../log/trace9 --trace-time http://127.0.0.1:43463/we/want/9 -F name=daniel
-F tool=curl -F file=_at_../log/test9.txt

With that, the stack trace on SIGSEGV is:

I am using the hardware randomizer source on x86. SSL 3.0.4 (in this case)
tests 100% correctly.
