Aborted (core dumped) with LV2

[fpesari]

I made an openSUSE package for the LV2 version of Surge and tried on Ardour, it crashes the program.

I then tried with all backends of jalv, it keeps crashing with these errors:

GTK:

GLib-GObject:ERROR:gvaluetypes.c:455:_g_value_types_init: assertion failed: (type == G_TYPE_CHAR)
Aborted (core dumped)

Qt:

*** Error in `jalv.qt5': corrupted double-linked list: 0x0000558a2a86ea30 ***
Aborted (core dumped)

• Surge Version: 1.6.2
• LV2
• 64 bit

My setup:

• OS: openSUSE Leap 15.1 (GNU/Linux, 64bit)
• Host Ardour
• Version 5.12.0

Tagging in @jpcima and @falkTX who worked on the LV2 port in this release.
Thanks for the clear bug report.

[falkTX]

are you able to get a gdb backtrace?

[fpesari]

are you able to get a gdb backtrace?

yes, I will try compiling it with debug symbols and report back

Well, I actually forgot to copy files in /usr/share/Surge, my bad 😆

It was an extreme reaction to that, though! Maybe Surge should warn and exit more gracefully if data files aren't found.

Oh you had the same problem as #1199!

If /usr/share/Surge is missing it pops user dialog saying fix that. That user dialog uses zenity and prints to stderr.

If zenity wasn't installed, though, we core dumped

@falkTX and I fixed that this morning - 77b9cb9

So you should be able to grab master, remove /usr/share/Surge/ and get a non-SEGV but non-crashing surge.

Can you confirm that for us?

[fpesari]

Can you confirm that for us?

Confirmed. Much better now! Thank you, also for the speed with which you replied! 😸

Great! We will sweep this fix into a point release this week - closing he issue

Thanks for the report!
