[TRE-general] segv from /usr/lib/libtre.so.4 (tre-0.7.5)

[Paolo]

hi,

while testing crm114 (crm114.sf.net) got segv from libtre:

$ gdb --args crm -w 8192 '-{window;isolate (:f:) /QUICKREF.txt/; match (:: :a: :b:) [:f:] /((?.+)^$.{10}).*/; output /:*:a:\n/}'

tarting program: /usr/local/bin/crm-btr -w 8192 -\{window\;isolate\ \(:f:\)\ /QUICKREF.txt/\;\ match\ \(::\ :a:\ :b:\)\ \[:f:\]\ /\(\(\?.+\)\^\$.\{10\}\).\*/\;\ output\ /:\*:a:\\n/\}

Program received signal SIGSEGV, Segmentation fault.

the guilty RE is '((?.+)^$.{10}).*'

that's on Debian Woody, gcc-2.95.4, tre-0.7.5
