Internal error when compiling OpenJade on Alpha/Digital Unix

[Stephane Bortzmeyer <bortzmeyer at pasteur dot fr>]

Hello,

Compiling OpenJade (a free DSSSL processor) 1.3
http://openjade.sourceforge.net/download.html

with:
gcc --version
2.95.2

on:
uname -a
OSF1 wallis.pasteur.fr V4.0 1229 alpha
sizer -v
Digital UNIX V4.0F  (Rev. 1229); Fri Nov 12 12:14:47 MET 1999 
	
yields:			
c++ -fno-implicit-templates -O2 -ansi   -I. -I./../include -I./../generic 
-DSP_HAVE_BOOL  -DSP_MULTI_BYTE -DJADE_HTML   -DSP_HAVE_SOCKET

Compiling with -O0 allows to compile this specific file, although it crashes 
later:

c++ -fno-implicit-templates -O0 -ansi   -I. -I./../include  -DSP_HAVE_BOOL  
-DSP_MULTI_BYTE -DJADE_HTML -DSP_HAVE_SOCKET -DSGML_SEARCH_PATH_DEFAULT=\"/loca
l/share/sgml\" -DSGML_CATALOG_FILES_DEFAULT=\"/local/share/sgml/catalog\"    
-o onsgmls nsgmls.o SgmlsEventHandler.o RastEventHandler.o StringSet.o 
nsgmls_inst.o  ../lib/libosp.a -lm
collect2: ld terminated with signal 10 [Bus error], core dumped

Sorry, I wasn't able to reproduce the bug on a smaller program.
