Comment # 2 on bug 1205577 from Stefan Dirsch

No idea why MAXFILES would be set to 256 in our build. Indeed in source code
it's set to 2048. Best would be to bisect the issue.

Possible candidates in git changes

After 1.0.5 and before 1.0.6

Subject: [PATCH 06/14] missing bounds check in makedepend for file arguments

When assigning source code files from the command line to the fp pointer,
no bounds check is done and if more than MAXFILES file names are specified
on the command line, memory will be overridden out of bounds.
