Bug #278: segmentation fault on regexp

• Status: Rejected
• Assignee: nobu (Nobuyoshi Nakada)

=begin
ruby segfaults when rexml tries to parse an xml document (which i can't post).

tracing the execution, the failure is in:
c-call /usr/lib/ruby/1.8/rexml/parsers/xpathparser.rb:605 === Regexp

this is inside a case statement on 'path' variable which is a String with value '*' (without quotes)

coredump shows this:
#0 0xb7e7cbca in re_match_exec (bufp=0x8109fb0, string_arg=0xb481a0c0 "", size=1, pos=0,
beg=0, regs=0xbfc4c5ec) at regex.c:3981

Didn't any other exceptions occur before the crash?

Rejecting this issue since it lacks the information necessary to reproduce it. Since the regex engine has been changed in 1.9, we can only assume that this bug is no longer present.
