Hi Richard,
I tried to create the RootApps but I ran into the following problems which
are likely strongly related. For Asc2root I get the following crash:
ylws41> ~/asc2root pyth_sugra.asc pyth_sugra.root
Welcome to asc2root.
Fatal in <operator delete>: storage area overwritten
aborting
Abort process
The same happens for fastmc:
ylws41> ~/fastMC /group/ppg/prj/lcd/lcd_input/pythia/std.output SmallTrackSmear.par out.asc
Fatal in <operator delete>: storage area overwritten
aborting
Abort process
The Event shared library was created successfully and it appears to work.
I have successfully used it in Root to read Root files of events.
****************************************************************************
When I build fastmc, the following warning (the first one) is common:

The crash is occurring in the root initialization. Instead of the full
asc2root routine I tried the stripped routine below which gives the same
error.
#include <stdio.h>
#include "TROOT.h"
main(int argc,char *argv[]) {
printf("Welcome to rint (ver 1).\n");
TROOT simple("simple","Example of creation of a tree");
return(0);
}
The link command I use for asc2root is:
$(exe): $(dirbinfiles)
if [ -f $(exe) ] ; then rm $(exe) ; fi
ld -L/usr/lib/cmplrs/cxx \
-rpath /usr/lib/cmplrs/cxx -expect_unresolved "*" \
-g0 -O1 -call_shared \
/usr/lib/cmplrs/cc/crt0.o /usr/lib/cmplrs/cxx/_main.o $+ \
-o $(exe) $(EVENTLIB) $(LIBS) -lcxxstd -lcxx -lexc -lots -lc
which produces:
ld -L/usr/lib/cmplrs/cxx \
-rpath /usr/lib/cmplrs/cxx -expect_unresolved "*" \
-g0 -O1 -call_shared \
/usr/lib/cmplrs/cc/crt0.o /usr/lib/cmplrs/cxx/_main.o ../bin/OSF1/rint_han.o \
-o ../bin/OSF1/rint_han

For asc2root, theree are no warnings/errors in the compiling or linking
but it crashes upon execution.
In the debugger, the traceback looks like:
