I receive a segfault in my program when I am trying to print out information on Throwable instance in a catch block.
The GDB backtrace:
Program received signal SIGSEGV, Segmentation fault.

The code 'src/les/ast.d' where the exception is caught and printed is (line 988, code 't.toString()') here:
981 try {
982 return runBuiltInCommand(execEnv, dCode, parameterTree);
983 }
984 catch (Throwable t) {
985 execEnv.context.callLocation.srcCode = STRING_EMPTY;
986 debug (echoToConsole) logError("EXCEPTION %s THROWN in BIC %s in method: %s\n%s",
987 t.classinfo.name, bicName[getBicNamePrefix().length+1..$],
988 >>> execEnv.context, t.toString().indent().chomp());
989 execEnv.requestLog.logError("EXCEPTION %s THROWN in BIC %s in method: %s\n%s",
