Something seems to go wrong with the intialization of a unit.

Because the fpc units are compiled without debug info, it is impossible to see which unit fails.

Can you recompile the fpc units with debug info?

[RNZ]

how can i'm recompile the fpc units with debug info?
in gentoo?

fpc_initializeunits..
what to do next?

[Vincent Snijders]

You just rebuild the Lazarus sources. You first need to rebuild the FPC sources to get more debug info.

[Vincent Snijders]

This is useful information. It seems to allocate a negative number of bytes in READTIMEZONEFILE.

Can you try to compile and run the following program?

Code: [Select]


program test;

uses unix;

begin
  writeln('Test');
end.


[RNZ]

Test program - compiled and worked ok:

Code: [Select]

rnz@rnzws ~/fpc-test $ cat test.pp
program test;

uses unix;

begin
  writeln('Test');
end.
rnz@rnzws ~/fpc-test $ fpc test.pp

Vincent, what do next?

[Vincent Snijders]

It is a pity that the test program works.

I have no knowlegde about the timezone initialization on freebsd, so I cannot see where the bug is.

Because the test program worked and Lazarus didn't, maybe there is some memory corruption going on. Can you try compiling lazarus with OPT='-ghl'?

[RNZ]

I'm update to gentoo-kernel-2.6.18-r4
and now runtime error - no.

[Vincent Snijders]

So, the update of gentoo fixed your crash?

[RNZ]

I think update kernel or glib (to 2.12.5) - solve problem

[Vincent Snijders]

Good :-)
