Bug#1019913: libsoup3: segmentation fault when using HTTP2

[Evangelos Ribeiro Tzaras]

Source: libsoup3
Version: 3.2.0-1
Severity: important
Forwarded: https://gitlab.gnome.org/GNOME/libsoup/-/issues/302

Dear Maintainer,

libsoup3 sometimes runs into a segmentation fault when using HTTP2
that can be worked around by forcing HTTP1 usage with the environment variable
SOUP_FORCE_HTTP1=1


Logs will show the following type of warnings:

libsoup-http2-WARNING **: 18:32:30.072: (../http2/soup-client-message-io-http2.c:410):io_read: runtime check failed: (io->in_callback == 0)

before running into a segmentation fault.


Thank you for your work on maintaining libsoup3
and especially your work on the recent transition!
