I couldn't find anything relevant in the "offending" function siInit() (defined in Singular/misc_ip.cc); AFAICS there are no local variables that could get corrupted at all in the function itself, so they apparently originate from macros or inlined functions, with debug info lost during optimization. So someone should really try to reproduce the error on 32-bit Ubuntu 14.04 or 16.04, or inspect the code generated by Ubuntu's GCC. -leif -- You received this message because you are subscribed to the Google Groups "sage-release" group.
