Descriptionwhile trying to visit my university's moodle page netsurf crashes every time
Steps To Reproduceopen netsurf and navigate to moodle2.uni-potsdam.de
Additional Informationnetsurf -v and gdb output (stock binary from archives) attached

gdb shows a free() error in context of ld-musl-i386.so.1

When I have the time to do it I'll compile netsurf with debug symbols enabled, as well as try to reproduce this bug on real hardware, different architectures and different Linux distros.

I reproduced the bug after building netsurf 3.8 from source on Debian 9.5.0 Stretch,
hence it does not seem to be ld-musl-i386.so.1 exclusive (/lib/i386-linux-gnu/ld-2.24.so is used in Debian)

I cannot reproduce this in the current development build.

However from the backtrace/valgrind logs you provided there is a suggestion that your build has libcurl compiled with a different version of openssl to the version used in netsurf.

Because we use libcurl openssl API the two versions *cannot* be different or odd crashes happen when getting prompted for ssl exceptions like on the website you link
