Hello,
This is similar to the issue seen here
(http://valgrind.10908.n7.nabble.com/valgrind-out-of-memory-error-td54401.html)
however I have compiled with n64 ABI and therefore should be supported.
When I attempt to use valgrind I get the following error:
==5133== Valgrind's memory management: out of memory:
==5133== newSuperblock's request for 4194304 bytes failed.
==5133== 27607040 bytes have already been allocated.
==5133== Valgrind cannot continue. Sorry.
I have run valgrind using strace (entire trace is pasted at the end of
the email) and I can see the execution tripping up on a call to mmap:
mmap(0x802001000, 4194304, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, 0, 0) = -1 EINVAL (Invalid argument)
At this stage I am not sure what is causing this problem? I have attached
'ulimit -a' and 'cat /proc/meminfo' below.
ulimit -a

-t: cpu time (seconds) unlimited
