Hi,
I just found out that ksh 2013-02-14, 2013-02-22 can't build ksh.
Version 2012-11-22 works fine.
When building ksh with 2013-02-?? in the environment, build fails:
+ iffe -v -X ast -X std -c 'cc -D_BLD_DLL -fPIC -D_BLD_ast -O2 -g -pipe

iffe: line 38: 7639: Memory fault(coredump)
Every iffe cc ends with sigsegv.
It happens when building using rpmbuild. Manual build does not seem to
trigger this.
Backtrace is:
