[Vm-dev] Fwd: [Pharo-dev] Pharo 7 Repeatable crash: XIO: fatal IO error 14 (Bad address) on X server ":0"

[Martin McClure]

Anyone here interested in this crash? Is there a newer VM I should test
with?

Thanks,

On the current Linux32 Pharo 7.0, (https://get.pharo.org/70+vm as of 30
minutes ago) the VM crashes with the message

XIO:  fatal IO error 14 (Bad address) on X server ":0"

whenever I try to enlarge the Pharo window by dragging the corner, and
get to a size of about 2Mpixels. This is with a virgin image with no
windows open inside the main window. A workaround seems to be to open a
System Browser before resizing the main window.

This does not reproduce on Pharo 6.1 (https://get.pharo.org/).

This *does* reproduce when running the Pharo7 image on the Pharo 6.1 VM,
so it may not be entirely a VM problem.

Most times, no crash dump is created, and nothing is logged to
PharoDebug.log.

Occasionally, especially when rapidly changing the size of the window,
it segfaults and logs a dump. This may or may not be the same problem. 


This is less annoying since I found the workaround, but still seems to
be something that should be fixed. Does anyone want further information
from me in order to fix it?

Regards,

-Martin
