I'm sorry, the breakpoint wasn't hit. what was the result of
gdb --args perl
symbol cygwin1.dll
define btc
# "Function "_sigfe_free" not defined." shouldn't be seen. if it does, please use latest snapshot including debug symbol.
b _sigfe_free
disp *((unsigned*)$esp+1)
#and just press enter until sigabrt is hit.
