Possible execve bug in Haiku

[miqlas]

Noticed it in fish shell, below the bugreport:

​https://github.com/fish-shell/fish-shell/issues/3645

Komment from ridiculousfish:

krader is right that execve is allocating memory, and I would tentatively argue that this is a bug in Haiku. In particular POSIX requires that execve is async-signal safe, which means it may be called from a signal handler, and thus must not call malloc internally.

Original bugreport, for the history:

Reproduction steps

write characters into your Terminal press Ctrl-C Repeat .... Profit! Fish hangs after Ctrl-C and aren't accept any input anymore, so you need to kill it. I never had any problems like this with the 2.3.x releases. (if i remember correctly.)
