It seems to be an error in libsoup. Attempt to fix it: https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/220

[Diego Pino]

This other test is also failing with the same stracktrace:

Another test failing with the same stacktrace:

imported/w3c/web-platform-tests/eventsource/eventsource-close.htm

https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/r277619%20(1816)/imported/w3c/web-platform-tests/eventsource/eventsource-close-crash-log.txt

[Diego Pino]

Gardened in r277632.

imported/w3c/web-platform-tests/eventsource/eventsource-close.htm started to crash in r277601.

This two tests stopped crashing around r277946 (updating to libsoup3)
