[Blitz-support] Followup to resize causing segfault.

[Eric O. <et...@sp...>]

I ran a little program through gdb and, here's a bit of the log:


  Program received signal SIGSEGV, Segmentation fault.
  0x40b97d3e in free () from /lib/libc.so.6
  (gdb) backtrace
  #0  0x40b97d3e in free () from /lib/libc.so.6

  #9  0x40b426cf in __libc_start_main () from /lib/libc.so.6



Line #7 is about the last place I really understand what's going on, that's
a line that asks for a resize.

Everything after that is voodoo to me.  :)


The blitz++ code doesn't seem too complicated to me at this point, and
the error actually appears to be thrown from libc ... does this mean a
bug in libc or am I clueless?



Thanks for any help.
