SIGSEGV of a2ps when compiled against bdw-gc on Solaris

[l1gi]

Hello,

I am trying to upgrade to a recent version of a2ps where bdw-gc is a mandatory dependency. I have successfully built and tested bdw-gc on recent Solaris:

$ gmake check

a2ps configure script has found libgc.so.1 and the whole package has built without issues. I am getting following SIGSEGV after trying to run the binary built:

Could you help me with debugging the issue, please? Should you need more information, dont't hesitate to ask.
