It did crash during this build, yes.  The solution provided once was to
set '-fno-optimize-sibling-calls', and this is what I usually do and it
works:

$ CFLAGS='-O2 -fno-optimize-sibling-calls' ./configure ...

Did you give me a recipe how to produce the backtrace from GDB?
Otherwise I'll go through this thread and look.
