Re: Built perl 5.6.2 on Cygwin 1.7.11, but get SIGABRT from resulting perl.exe

[Nicholas DiPiazza <nicholas.dipiazza@openlogic.com>]

Jojelino asked:

  "and then, what was the result of
  gdb --args perl
  b _sigfe_free if *((unsigned*)$esp+1)==0x20000010 #which i am interested in to see what the backtrace was. 
  disp *((unsigned*)$esp+1)
  r
  bt #when breakpoint is hit"


Here is the result: 

$ gdb --args perl
