Thanks.
<span class="quote">> I hope apitrace was invoked right ...</span >
Yep, it reproduces the issue fine:
$ glretrace konqueror.trace
src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c:1887:lp_emit_declaration_soa:
Assertion `idx < 256' failed.
apitrace: warning: caught signal 5
1585: error: caught an unhandled exception
apitrace: info: taking default action for signal 5
Trace/breakpoint trap
One can see the expected output by doing (on a non-crashing driver like
NVIDIA):
$ glretrace -S 1585/draw konqueror.trace
