Possible bug in glibc

[miqlas]

Fish crashing if i close the terminal, i try to hunt this bug down since ages, see here: ​https://github.com/fish-shell/fish-shell/issues/4099

Some people meant it could be a bug lurking in Haiku's glibc implementation, so i tried to run and get it crash normally, then with

LD_PRELOAD=/system/lib/x86/libroot_debug.so fish

and the like:

MALLOC_DEBUG=g LD_PRELOAD=/system/lib/x86/libroot_debug.so fish

You can find the debug logs in the attachement, but i copy the most relevant part here from the output of the "MALLOC_DEBUG=g LD_PRELOAD" command:

Does it ring a bell for somebody?

Can you eventually attach the files at ​https://github.com/haikuports/haikuports/issues/1801 ?

Should we mark this as beta-blocker?
