#31 TSIPP: SippBlock causes a memory leak

[Paul Douglas Welton]

Run the program tksipp. The following command causes
a substantial memory leak, as observed with "top":

for {set i 0} {$i < 10000} {incr i} {
SippReset
SippBlock {0.1 0.1 0.1} \
[SippShaderBasic 0.5 0.1 0.1 {0.3 0.3 0.3} 1.0]
}

while the following command does not:

for {set i 0} {$i < 10000} {incr i} {
SippReset
SippCone 0.5 0.5 6 8 \
[SippShaderBasic 0.5 0.1 0.1 {0.3 0.3 0.3} 1.0]
}

The implication for the TSIPPwb user is that if
automatic rendering mode is used for a scene with many
Cuboids, memory usage will increase, and if it reaches
a system limit, the program will be killed.

WORKAROUND

Monitor memory usage using "top". If it appears
excessive, save the work and quit from TSIPPwb and
reload.
