This is an outfall of bz #4920 where I try to debug bash and examine a variable
in the (main). Once the core file is dumped I try to look at the core file with
fstack and it aborts like this:
./build/frysk-core/frysk/bindir/fstack -a core.18293
Task #18293
#0 0x00110402 in __kernel_vsyscall () from
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

Attaching the corefile won't work, without corresponding exe and solibs that
match it. This might be an issue of automatic exe locaiton.
Can you attach the output of:
eu-readelf -n core.18293

Conextually however the should be "available scopes" safety check in this code:
DwarfDie[] scopes = bias.die.getScopes(getAdjustedAddress());
for (int i = 0; i < scopes.length; i++) {
if (scopes[i].getTag() == DwTagEncodings.DW_TAG_subprogram_) {
subprogram = new Subprogram(scopes[i], debugInfo);
break;
}
