Hi,
I tried to build Isabelle 2011-1 with the repository version 1352 of PolyML on
Ubuntu 10.04 and x86_64. g++ seems to include its fortify checks automatically
in the compiled code. When I build Isabelle's Pure session, it detects a buffer
overrun and aborts PolyML. Is this a bug in PolyML? Or does PolyML not work with
Fortify? Or is it just a misconfiguration on my side? If I disable fortify with
-D_FORTIFY_SOURCE=0 when compiling PolyML, everything works fine again.
At the end of this mail, I have included the stack trace and memory map for the
buffer overflow.
Best regards,
Andreas
