gdImageChar* crash
Issue #57
resolved
gdFontTiny, Small, Large and Giant are 0x0 instead of a ptr to the font table.
Using current master and running php with bug19366.phpt f.e. reproduces the crash

shouldn't these things be declared static/const ?

Declare exported variables as extern in *.h files (fixes
#57)→ <<cset e0659e5d3499>>

Account Deleted Could you try now? I suspect that it was the missing extern in header files which redefined the pointer to a local NULL value (which is default from C89 I think).

Using gdFontGet* just works. I suspect the export data macro being wrong.
