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 \

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...

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
mystified.
