--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
Here's what gdb tells me about that segfault when I compile from source =
and run
the unstripped binary:
Program received signal SIGSEGV, Segmentation fault.
0x4009b10b in mallopt () from /lib/libc.so.6
(gdb) where
#0 0x4009b10b in mallopt () from /lib/libc.so.6
#1 0x40099edf in free () from /lib/libc.so.6
#2 0x400de2ae in regerror () from /lib/libc.so.6
#3 0x400de3e8 in regfree () from /lib/libc.so.6
#4 0x0804c7be in crm_invoke ()
#5 0x08049430 in main ()
#6 0x4003eda6 in __libc_start_main () from /lib/libc.so.6
Here's the relevant part of incoming.crm (note that line numbers =
reported=20
by crm114 -t seem to be wrong):
$ sed -n 34,37p bin/incoming.crm=20
isolate (:stats:)
classify ( junk.css | good.css ) [:m_text:] =
/[^[:space:][:cntrl:]"=3D>]+/
goto /:appears_to_be_junk:/
}
I can also supply the content of the .css files and the message which =
causes this
segfault, if needed.
Thanks,
