Bison-2.1 segmentaion fault on AIX5.2 32 bit using xlC_r (Visualage 8)

[Saurabh Bhatnagar]

Hi,

 

I get this error only on AIX5.2 64 bit (AIX5.2 32 bit, RHEL 4.0, SUN 9.0, HP
Itanium 32 and 64 bit pass) The debug core analyzed points to the line  2980
in bison-2.1/src/scan-gram.c

 

memset((yy_buffer_stack), 0, num_to_alloc * sizeof(structyy_buffer_state*));

 

$ dbx /tools/rd/yacc-lex/v2.1_64/bin/bison core Type 'help' for help.

Hi,

 

the bison is used to create a cpp file from a ycc file.

 

 

 

scons: Reading SConscript files ...

 

scons: invoked with options: --debug=nomemoizer --debug=time -k
cmdinfo=default timestamp=yes type=B009 mode=Release plat=AIX5L_64

scons: *** [buildout/AIX5L_64/Release/nmx/process/nmxidl/grammar.cpp] Error

When I execute this command line I get Segmentation Fault as well.

Could not find much on AIX pages on this error..
