[GiNaC-devel] Crash during startup

[Richard B. Kreckel]

Hi!

Checking out a fresh GiNaC-1.3 tree and configuring --disable-shared
(after having called autogen.sh) leaves one with three crashing binaries
in the test suite.  It seems to be independend of compiler flags.  A
shared library works, as does ginsh.  (@Jens and Cebix: I reproduced this
on wino.)

A stack backtrace indicates that GiNaC::basic::gethash() is being invoked
on NULL:

(gdb) run
Starting program:
/autofs/medium/home/kreckel/projects/GiNaC-1.4/check/checks

Program received signal SIGSEGV, Segmentation fault.

Are we still having initialization order problems?
