Re: perl5.8.8 SEGfault and corrupt stack

 I'm having problems with perl5.8.8.  I tried running it under gdb, but
it won't load:

GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special)
(gdb) g
Undefined command: "g".  Try "help".
(gdb) run
Starting program: /usr/bin/perl.exe

Program received signal SIGSEGV, Segmentation fault.
0x610b48b6 in pthread_key_create () from /usr/bin/cygwin1.dll

Cannot reproduce. Is this a fresh re-install without site_perl or with your broken setup as stated in perl5-porters?

I also tried profiling a perl file:

law/perl> perl -d:DProf show.pl -s
8 [main] perl 3192 _cygtls::handle_exceptions: Error while dumping state (
probably corrupted stack)
Segmentation fault (core dumped)


Any ideas on causes...fixes?...
Thanks,
Linda

I would try a rebaseall


cygcheck output attached -- could NOT include it -- Tbird kept crashing.
(1st try composed message, copied in text, tried to address, and I'd
typed "c" and it autocompleted cygwin... first of 3 dropdown items.
That hung...full cpu usage. (lost email)
(2nd try, recomposed email, *saved*, then tried to address it: another hang.
(3rd try, put in to addr 1st!...then tried to paste text into window..3rd hang
(4th try, try to "re-edit" the saved message -- that hangs (I can display it in
my Drafts folder), soooooo....
5th try: just put in body and attach cygcheck_output.txt as an attachment.
...(hopefully this works)
