Bug#855080: giac: FTBFS on hurd-i386: Too many recursion levels Error: Bad Argument Value

[Aaron M. Ucko]

Source: giac
Version: 1.2.3.25+dfsg1-1
Severity: important
Justification: fails to build from source

The build of giac for hurd-i386 (admittedly not a release
architecture) failed with many errors along the lines of

Unable to eval 1/(x^4-1)^10: Too many recursion levels Error: Bad Argument Value

as detailed at
https://buildd.debian.org/status/fetch.php?pkg=giac&arch=hurd-i386&ver=1.2.3.25%2Bdfsg1-1&stamp=1486947346&raw=0

(affecting every top-level test, and what appears to be nearly all
individual cases).

Could you please take a look?

Thanks!
