Description
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.

Research direction
Start by reproducing the failure using the Convex test block linked in the report on Julia 1.9.2 and Apple silicon, then compare ECOS with Clarabel. Done means producing a minimal reproduction or confirming the location and cause of the freed-object checksum failure, with the malloc_error_break debugging guidance investigated.
