This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.5.
-----------------------------------------------------------------
When building perl 5.8.7 with the -fstack-protector patches for GCC,
miniperl fails to build DynaLoader and segfaults. This didn't happen
with 5.8.6.
Here's a backtrace of the crash in miniperl.
Starting program: /usr/src/perl-5.8.7/miniperl "-I../../lib"
"-I../../lib" ../../lib/ExtUtils/xsubpp -noprototypes -typemap
../../lib/ExtUtils/typemap DynaLoader.xs > DynaLoader.xsc && mv
DynaLoader.xsc DynaLoader.c
Program received signal SIGSEGV, Segmentation fault.
