| Steps To Reproduce | Our best results at reproducing the crash are by 'grepping' big files/input's. | ||||
| Additional Information | Mud is running in "UTF-8 mode" but pretty much all files are ascii encoded. Core dump is available upon request | ||||

Could you please provide the coredump and corresponding binary? |
|
|
New infomation has come to light. The crash might be due to a Python efun function (grep tool) that looks like this: def do_grep(name, where, arg): myCmd = os.popen('grep --include \*.h --include \*.c '+arg+' '+name+' /mud/lib'+where).read() myOutput = re.sub('/mud/lib','',myCmd) myOutput = re.sub(name, '%^BLDCYN%^'+name+'%^OFF%^',myOutput) return myOutput Binary and core: https://nas.zitz.dk/~ralph/ldmud https://nas.zitz.dk/~ralph/core |
|
|
I could download the binary, but I get HTTP 403 for the core. |
|
|
Apologies, the permissions on the file were too restrictive. Please try again |
|
|
The binary and core file don't seem to match. According to the core file the binary was named "dev-ldmud", is this a different one? |
|
|
#Gnomi - dev-ldmud is a symlink: dev-ldmud -> ldmud |

Fixed in the current master. |
