hi,

I'm using pcregrep the following way:

gdb --args pcregrep -M 'va_start(.|\R)*va_end' someFileContainingIt.c
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff79bba52 in ?? () from /lib/libpcre.so.3

They backtrace hints at a stack recursion, so the impact could be a DoS.

pcregrep version 7.8 2008-09-05
Ubuntu Version: 7.8-3build1

Best,
Felix
