           Summary: crash on large result, "exp" operation
           Product: kcalc
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kniederk mi uni-koeln de
        ReportedBy: ebachmann netandweb de


Version:           2.0.4 (using KDE KDE 3.5.4)
Installed from:    Gentoo Packages
Compiler:          gcc-4.1.1 
OS:                Linux

enter a large number (say 1000), then hit "Inv", then "e^x" => Kcalc crashes.

according to GDB the crash occurs in:
#0  0x000000354b90cbd9 in raise () from /lib/libpthread.so.0
#1  0x000000370ea07d0e in __gmp_invalid_operation () from /usr/lib64/libgmp.so.3
#2  0x000000370ea09aed in __gmpf_set_d () from /usr/lib64/libgmp.so.3
#3  0x0000003478158d8c in KNumber::KNumber () from \
/usr/kde/3.5/lib64/libkdeinit_kcalc.so #4  0x000000347813c2be in CalcEngine::Exp () \
from /usr/kde/3.5/lib64/libkdeinit_kcalc.so #5  0x000000347814abdb in \
KCalculator::slotLnclicked () from /usr/kde/3.5/lib64/libkdeinit_kcalc.so

Seems like its not generally a problem with the result value, as kcalc can calculate \
e.g. 10^1000000 just fine.
