Not sure if this is where I should report, but I have a segfault in reportlab userguide creation with 3.10a4. I am getting this info from coredumpctl running archlinux with
Linux hostname 5.10.6-arch1-1 #1 SMP PREEMPT Sat, 09 Jan 2021 18:22:35 +0000 x86_64 GNU/Linux
the error is Message: Process 1530711 (python) of user 1000 dumped core.

1) I compile this from source using the standard LTO method my script looks like
###### #
CFLAGS="-march=x86-64 -mtune=generic -O3 -pipe -fno-plt -fno-semantic-interposition" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -rpath=$HOME/LOCAL/3.10.0a4/lib -fno-semantic-interposition"
./configure \ --prefix=$HOME/LOCAL/3.10.0a4 \ --with-computed-gotos \ --enable-optimizations \ --with-lto \ --enable-ipv6 \ --with-system-expat \ --with-dbmliborder=gdbm:ndbm \ --with-system-ffi \ --with-system-libmpdec \ --enable-loadable-sqlite-extensions && make EXTRA_CFLAGS="$CFLAGS" && make install

1) can I get more information using a different compile setup
2) or can I get more information with the python run. I just used
$ python genuserguide.py Built story contains 1843 flowables... Saved "/home/robin/devel/reportlab/REPOS/reportlab/docs/reportlab-userguide.pdf" free(): invalid pointer Aborted (core dumped)
3) I am running in an old style virtual environment generated using a modified virtualenv 16.2.0 (to fix wrong usage of sys.version[:3] in path names)
4) All other tests seem fine including tests of image generation and the accelerated strinGWidths etc etc so I am a bit
