Hi.
I have been experimenting recently with jemalloc heap profiling, as way to
debug memory leaks, but unfortunately it crashes quite frequently.
CPU architecture is PPC , below is a typical backtraces I get - looks like
the stack is corrupted.
Program terminated with signal 11, Segmentation fault.
#0 0x0ffaab14 in je_prof_backtrace (bt=dwarf2_read_address: Corrupted
DWARF expression.
) at prof.c:398
..
#3 0x0ff7691c in je_choose_arena (arena=<value optimized out>)

#6 je_imalloct (arena=<value optimized out>, try_tcache=<value optimized

#7 imallocx (arena=<value optimized out>, try_tcache=<value optimized

jemalloc.c:1421
#8 imallocx_prof_sample (usize=dwarf2_read_address: Corrupted DWARF
expression.
) at jemalloc.c:1436
...
Can anyone tell if this is a known problem and if can be overcome ?
Regards,
Martin.
