Re: Perl build fix attempted

Further digging: the backtrace from the SIGSEGV looks like

#0 0xc00a02fc in ?? () from /usr/lib/libc.1

Since gdb doesn't really know anything about code generated by HP's cc,
it's difficult to get any more info than this. However, the fact that
the crash is inside malloc() suggests a memory clobber very strongly.
My best theory at this point is that there's some conflict of ideas
about the size of data structures, perhaps triggered by those missing
-D symbols ...
