Hi all,
My config : Ubuntu Linux 8.04, gcc 4.2.4, qt 4.5.0-rc1, SQLServer 2000
on a W2K3 Server & unixODBC / freeTDS.
I'm accessing the database without problems, with QODBC Driver. With
Qt-4.4.3, I can use those selects without problem :
SELECT CAST ( 1.1899999999999999 AS FLOAT ) AS V1
SELECT CAST ( 1.1463600047577465 AS FLOAT ) AS V1
When I switched to Qt-4.5.0-rc1, the second one hangs !! It happens only
with float values.
Backtracing with gdb some selects with float results, I've this output
( it's from another test, with a table that has more columns, so don't
bother about the param column=70 shown )
#0 0xb69f69bc in memcpy () from /lib/tls/i686/cmov/libc.so.6

colSize=10, unicode=false)

kernel/qsqlquery.cpp:395
#5 0xb68fa167 in QSqlQuery::record (this=0x86394e4) at
kernel/qsqlquery.cpp:847
I've been looking inside Qt code, but I can't found what's happening.
I'm wondering about this. Any clues ?
Many thanks,
Jordi Pujol.
