Summary0000871: ldmud 3.6 compiled with gcc 9.2 segfaults at start (probably due to memory allocator)
DescriptionI build the ldmud with settings/morgengrauen. Afterwards execution of ldmud immediately segfaults.
When I add with_malloc=sysmalloc to settings/morgengrauen after Zesstra's suggestion, this error disappears. Happens with current git version (I actually tested multiple checkouts on the master branch).
Steps To Reproducegit clone https://github.com/ldmud/ldmud.git
cd ldmud
settings/morgengrauen
make all
./ldmud

Faulty ldmud binary is somewhat temporarily available under

If it's broken mud tm deaddy@morgengrauen or tizona@morgengrauen so I can restart the server, at least a few days it should be able to reside there.

Could you please try the following branch: https://github.com/amotzkau/ldmud/tree/871-nullpointer
I don't have GCC 9 to check for myself.

I can't build that one because of openssl:
make: *** [<builtin>: pkg-openssl.o] Error
IIRC I only managed to build 3.6 versions since some openssl update.

I don't understand. My branch is just the master you built with a few lines in slaballoc.c changed. Nothing related to openssl.

Excuse me, I forgot to checkout the branch.

That seems to fix it.
