Incorrect checksum for freed object #144

Open ericphanson opened 1 year ago

ericphanson commented 1 year ago

On Julia 1.9.2 on apple silicon, I got this error

julia(65496,0x16b3f3000) malloc: Incorrect checksum for freed object 0x2c2baa688: probably modified after being freed.
Corrupt value: 0x14293a
julia(65496,0x16b3f3000) malloc: *** set a breakpoint in malloc_error_break to debug

[65496] signal (6): Abort trap: 6
in expression starting at REPL[16]:1
Allocations: 256785273 (Pool: 256509945; Big: 275328); GC: 452
zsh: abort      julia --project

when running Convex tests with ECOS (specifically this code on the linked commit). The same tests with Clarabel are OK.

I don't know how to

set a breakpoint in malloc_error_break to debug

but if someone wants to walk me it through I'm game.

Oh yeah this is not easy to debug. You'll need the exact model that's failing, an M1 machine and a locally compiled version of ECOS...
