PlatformOSMac-OSX-10.2OS Version
Summary0000127: Labels in record shapes limited to ~1500 characters
Description



dot version 1.8.6 (Sun Jun 23 12:25:06 CEST 2002)



It seems that the labels of of vertices in dot (at least when using the
record shape) are limited in size to about 1500 characters. For any normal
label, this length seems adequate. However, when using the record shape it
is somewhat limiting, especially when whitespace is added to make the dot
file easier to read.



Here's the error I get:
<CD>
*** malloc[12295]: error for object 0x8a7e0: Incorrect checksum for freed
object - object was probably modified after being freed; break at szone_error
Segmentation fault
</CD>



I'm running dot on Mac OS X 10.2 on a 450Mhz PowerMac G4 with 512 MB memory.
Additional Information

I'm including a graph that doesn't work. Remove the last line in the record
label and it should work just fine.

We're using dot to help us debug a VLIWish compiler. Hence the large blocks
and the pseudo op codes.
TagsNo tags attached.

FIX-COMMENT 
Feels like a buffer overflow error. (how about partial credit :)

[erg] We have fixed various things since 1.8.6 and Preston reports
that it's okay in 1.8.10.
