RuntimeError: memory access out of bounds

[Redrrx]

Hello

I am trying to check a chromium build (29mb) graph using this

perf record -F 999 -g -- ./chrome --user-data-dir=/tmp/chrome-prof

perf script | ~/FlameGraph/stackcollapse-perf.pl --all > chrome.folded
but when i upload i get this error and the websites loads the bar and it stops

Uncaught (in promise) RuntimeError: memory access out of bounds at 00043e86:0x615e at S.E.wasm_demangle (demangle.wasm.js:5:97085) at demangle.ts:20:16 at b.demangle (profile.ts:419:22) at async vn.loadProfile (application.tsx:215:7)

hi @Redrrx, thanks for reporting!

if you can provide a profile file I can drop into speedscope and see the crash, I'm far more likely to work to address this

It looks like this might be the same issue as #507
