It's entirely reproducible.  I've filed
https://bugzilla.redhat.com/show_bug.cgi?id=1566242 with what I can glean.

I don't understand the backtrace though.  Seems like a destructor is getting
called when initializing a class variable.  Very strange to me, but I'm no C++
expert.

Re: New gdl segfaults with gcc 8 in antlr

I've just discovered that gdl appears to be segfaulting a lot now deep in the 
antlr c++ generated parser code with the switch to gcc 8.


A bugzilla report would be nice.  Run under gdb, report register contents
and the instruction stream surrounding $pc, etc.  Also any clues
about the corresponding location in the source code.

Is the SIGSEGV deterministic (reproducible every time) or random?
Does memcheck (valgrind --track-origins=yes) complain?

New gdl segfaults with gcc 8 in antlr

2018-03-28 Thread Orion Poplawski
I've just discovered that gdl appears to be segfaulting a lot now deep 
in the antlr c++ generated parser code with the switch to gcc 8.  Has 
anyone else run into similar issues?
