When trying to do a keyword search of the gcc docs I get a core dump with the message: "*** glibc detected *** double free or corruption (out): 0x00000000000550790 ***" Reproducible: Always Steps to Reproduce: 1. Type "pinfo gcc<CR>". 2. Scroll to last link, "Keyword Index" on the rsulting page. Select it and press <CR>. 3. Select any item, e.g. "Multi-alternative". Press <CR>. 4. Get core dump. Actual Results: I get a core dump with the message: "*** glibc detected *** double free or corruption (out): 0x00000000000550790 ***" Expected Results: I would expect to get to the appropriate page in the documentation.

No metadata.xml - agriffis, it's your lucky day :P
no thanks, please reassign
Attempt #2 - aliz, you keyworded it amd64 ;-)
Created attachment 59128 [details] Valgrind report of 'pinfo gcc' This is a report produced by Valgrind running 'pinfo gcc' and performing the actions described in the first post of this bug. After not crashing pinfo is closed by pressing 'q'.
I can reproduce the crash with a 32-bit x86 system. I've compiled pinfo with -g and disabled stripping. I run pinfo just as described in the first message, attach gdb and trigger the crash just like in the first message. Stack trace shows: Program received signal SIGSEGV, Segmentation fault. 0xb7eb46f7 in mallopt () from /lib/tls/libc.so.6 (gdb) bt #0 0xb7eb46f7 in mallopt () from /lib/tls/libc.so.6 #1 0xb7eb3549 in free () from /lib/tls/libc.so.6 #2 0x0804be4a in freeitem (type=0xb7f64ff4, buf=0x80ab310, lines=0x418) at filehandling_functions.c:184 #3 0x0804be9b in read_item (id=0x8078840, type=0xbffff5dc, buf=0xbffff5e0, lines=0xbffff5e4) at filehandling_functions.c:203 #4 0x0804a35e in main (argc=2, argv=0xbffff794) at pinfo.c:333 Please see my Valgrind report above also.

(In reply to comment #4) > Attempt #2 - aliz, you keyworded it amd64 ;-) Apparently bad choice, MIA since January...
pinfo-0.6.9 was released: http://pinfo.alioth.debian.org/
I'll take this up. :)
Fixed in app-text/pinfo-0.6.9. Thank you for reporting this bug!
