Can you extract the command line and run it by hand?
Yes. I do see that snc crashes with both versions of EPICS when I run
the command in my terminal.
(Just trying to be helpful. Michael already asked for the core file)
Otherwise you may be able to run the compiler under gdb ?!?
To re-iterate, the problem is not the crash itself which was easily
fixed and purely my fault. Sorry for being unclear on this point. I have
fixed the subject line accordingly.
The problem (and mystery!) is the absence of any message in the make
output under 3.15 that would indicate that snc crashed; whereas under
3.14 I do see such a message in the make output. I can reproduce this
behavior reliably, regardless of the -j and -s make switches. My
conclusion is that something was changed in the build system between
3.14 and 3.15 that causes the crash message ("segmentation fault (core
dumped)") to be suppressed, probably as an unintended side-effect.
Cheers
Ben
