I have the libc compilled with "MALLOC_DEBUG" flag to detect double free. When i run this piece of code (attached file) thought GDB, i have this=20 assertion : Assertion failed: ((run->regs_mask[elm] & (1U << bit)) =3D=3D 0), function= =20 arena_run_reg_dalloc, file /usr/src/lib/libc/stdlib/malloc.c, line 2543. But when i run the same binary without GDB, no assert. I'm very confused. Can you help me to debug that ? Best regards =2D-=20 Alexandre Martins NETASQ -- We secure IT --Boundary-01=_aliXPnKyhLuiC9U-- --nextPart4136842.SocrAYyRgt--
