==12593== Valgrind's memory management: out of memory:
==12593==initialiseSector(TC)'s request for 27597024 bytes failed.
==12593==  629,841,920 bytes have already been mmap-ed ANONYMOUS.
==12593== Valgrind cannot continue.  Sorry.

^ Are you just running out of memory?

[kdevelop] [Bug 362062] Kdevelop crashes when on 4.7.1 when we try to open it with memory leak checking application valgrind

[Kevin Funk via KDE Bugzilla]

--- Comment #9 from Kevin Funk  ---
Sorry, still no useful backtrace.

Just run `valgrind --smc-check=all-non-file kdevelop`, this should already give
you a proper backtrace when it crashes. No GDB involved.
