Description Lyude 2015-11-19 20:13:08 UTC

Description of problem:
Valgrind fails to run weston (and probably other programs), crashes with the following message:

--28264:0: aspacem Valgrind: FATAL: aspacem assertion failed:
--28264:0: aspacem   ! is_freeslot(ix)
--28264:0: aspacem   at m_aspacemgr/aspacemgr-segnames.c:223 (get_refcount)
--28264:0: aspacem Exiting now.

Version-Release number of selected component (if applicable):
valgrind-3.11.0-1.fc23
Git snapshot of weston from http://cgit.freedesktop.org/wayland/weston/commit/?id=870fadced3f19659b60574888432b79713776097

How reproducible:
Always

Steps to Reproduce:
1. Build weston in it's own prefix based off the git commit linked
2. Try to run it under valgrind
3. Crash

Actual results:
Valgrind crashes

Expected results:
Valgrind should be able to run the program normally

Additional info:
I've confirmed this isn't a bug in weston itself, and is actually a regression with the valgrind package. If I try an older valgrind build for the fedora 23 beta from http://koji.fedoraproject.org/koji/buildinfo?buildID=678500 valgrind is able to run weston without any issues.

Comment 1 Mark Wielaard 2016-01-15 14:11:44 UTC

Note you don't have to build weston from scratch to replicate.
Using the weston package from fedora also triggers it when using the X11 backend (thanks to Tom Hughes for suggesting to try that out).

weston-1.9.0-1.fc23.x86_64
valgrind-3.11.0-1.fc23.x86_64

valgrind weston --backend=x11-backend.so
