[MiNT] Mintlib / posix regex / alloca and malloc

[m0n0 <ole@monochrom.net>]

Hello,

what reasons are there why the mintlib is compiled without support for 
malloc? Currently it uses alloca.
Netsurf crashes with some pages when used with mintlib regex + alloca 
(the crashes can be avoided (sometimes) by setting the stack really big 
(3MB and more...), but it's not a real solution...). When mintlib get's 
compiled with -DREGEX_MALLOC all the pages known to trigger the error 
are working fine.

The only thing which I can think of is speed & memory fragmentation. 
But on the other hand, I don't believe that someone uses his/her atari  
24h a day / 360 days a year... so memory fragmentation maybe isn't that 
important.

the other thing is speed, but I would prefer a stable regex 
implementation over one that has bugs.

What do people think, would it be good to make REGEX_MALLOC the 
default?

Greets,
